In the Himalayan region of Nepal, stone masonry has been used for centuries as primary building material structures with or without mud mortar. three distinct remote rural villages, a thorough structural survey approximately 223 buildings was conducted an emphasis on their irregularities. The thickness walls frequently varied between floors, which caused mass Openings in front wall were not symmetrical vertical direction, in-plane discontinuity. There also out-of-plane offset irregularities...

A subsurface investigation was conducted to assess the suitability of a site for potential tunnel construction, focusing on determination shear wave velocities (Vs) in materials. This study employed three distinct methods analyze Vs weathered soft rock: drilling mechanism, multichannel analysis surface waves (MASW), and microtremor array measurement (MAM). Through utilization MASW MAM, empirical relationships were established, enabling based solely soil type depth, offering practical...

The paper focused on the old traditional buildings, which were constructed more than 100 years ago. Some of these buildings partially destroyed in 1934 AD earthquake and some them survived without substantial damage. These unreinforced brick masonry are vulnerable to seismic hazard especially when they un-reinforced special consideration design. building extensively being used occupied by different governmental public offices. built with best available material during time construction...

This study focuses on the design and stability analysis of underground structures in Lesser Himalayan Region Nepal. The rock support for such opening depends upon mass strength. In this a proposed Kathmandu University Geo-Lab tunnel cavern, which passes through weak conditions, was used as case study. Existing empirical analytical methods cavern are estimation pressure support. A detailed numerical carried out 2D finite element to region. results showed that deformation can be predicted very...

This study focuses on the performance of Micro-Hydropower Plant (MHP), upto 100 kW, system in terms overall efficiency, that is, water- to- wire efficiency. MHP has been playing a significant role for electrification remote rural areas Nepal. Generally, 50 % efficiency is adopted while designing without consideration sizes plants due to lack testing facilities such domestically made turbine before installation. The field test was conducted, each individual powerhouse, using additional dump...

The power of the Distinct Element Method (DEM) in solving stability underground powerhouse caverns (UPC) is discovered, but when does DEM need to be adopted? What problems can solved? flowchart provided and applied analyze UPC this paper. With guide flowchart, damage index ( Di ) used as a failure type (gravity‐controlled or stress‐induced) judgment indicator. Through calculation three typical engineering, random blocks stability, dynamic calculation, support system evaluation are studied,...

Abstract Design of powerhouse is a major concern in hydropower project located Nepal Himalaya. seismically active zone. The structures built this region have to be seismic resistant addition dynamic loads, produced power house due the vibration turbine and generator set. structural elements such as slab, column, foundation, wind cover, wall need sustain vibration. It should also earthquake at same time. Using finite element methods, transmission was analyzed for selected case study lesser...

Abstract Several seismic codes are implemented for the design and construction of superstructures in Nepal but there is no guideline shallow tunnels which often constructed using conventional engineering approaches. The uniform hazard spectrum was obtained after performing a Probabilistic Seismic Hazard Analysis at Dhulikhel target estimated by comparing it with recommended code Building Code NBC 105:2020 Indian standard IS 1893:2016. average response from ten recorded earthquake ground...

Abstract Design of unreinforced masonry buildings is a major concern in seismically active zones Nepal. The ChandraJyoti Jalvidhyut Power House, historical landmark Nepal, represents the nation’s pioneering effort hydropower generation and signifies its rich cultural heritage. This study comprehensively assesses structural assessment seismic performance deficiencies House. Material tests on bricks with individual properties behaviour construction materials were done. Utilizing finite element...

Abstract. Nepal annually invests millions of dollars in hydropower development, with a substantial portion these funds allocated to civil infrastructure. Climate change, which impacts geological and hydrological conditions, poses threat components throughout project construction operation. This causes budget overruns, delays, adverse consequences for society the environment, ultimately resulting multimillion-dollar losses. The identification risk factors their underlying causes, stemming...

Abstract. The backwater effect can be caused by a number of factors, including the bridge's pier width and deck level. In lowland regions, particularly problematic, as it lead to flooding inundation farmlands houses. This study examines impact bridge structure on in region Shreekhandapur, Kavre, Nepal. area is characterized hill slope inner river valley, with gentle profile that results low flow velocity increased deposition. compares an old demolished four piers 1.2 m abutments both sides...

Abstract This study focuses on the seismic assessment of underground structures in transition Higher Himalayan and Lesser region Nepal. Due to fragile geology Himalaya, most are constructed highly jointed rock mass. Rock mass classification approaches extensively used for estimation supports without consideration. Design like tunnels cavern effect is rarely considered Nepal Himalaya. For sustainable development hydropower project tunnel caverns plays vital role terms its stability. Presence...

Abstract Tunnelling through faulted rock mass is associated with long lasting displacements, stability problems, overburden squeezing, high deformations and dynamic stress conditions. With the dominance of faults in Nepal Himalaya, determination behaviour around tunnels physical parameters for tunnel support very challenging demanding. Tunnel are always dominated by fault. In this paper a hydropower vicinity fault has been used as case study design application support. Rock characterized,...

Abstract Due to steep terrain and fast flowing rivers in the Himalayan region of Nepal, medium mega size hydropower projects are constructing day-by-day. Tunnel is one best short routes for water conveyance system power production. Hundreds kilometers tunnels have been constructed new planned this region. The availability high head generation, tunnel cross sections relatively small, up 6 m diameter size, there rock cover above alignment. This paper focuses on design construction practices...
