The mechanical properties of waste materials are, typically, believed to be more variable than natural soils; however, detailed investigations into the variability these is generally unavailable. shear wave velocity and its variation with depth laterally for five different types has been measured analyzed at 26 locations. Shear measurements were performed using multichannel analysis surface waves (MASW) microtremor method (MAM) techniques. Statistical analyses locations as well available in...

This paper presents a comprehensive study of the dynamic responses machine foundations, both block and pile on stratified residual soils in Duri Ulubelu, Indonesia. The evaluation was conducted using two widely recognized methods: lumped mass method (LMM) finite element (FEM). LMM FEM were performed by utilizing DYNA ABAQUS, respectively. analysis results showed that generally predicted more conservative displacements compared to FEM. conservatism displacement pronounced for group which are...

Seismic site response analysis is used to estimate the of soil deposits during seismic loading at any depth interest and interpret time histories as well spectra. This type involves many parameters that can affect character ground shaking. It important know effect these in order perform reliable hazard evaluation a site. paper presents effects several toward characteristics surface spectra based on local conditions Jakarta using one-dimensional (1-D) model with total stress approach.

This paper presents the application of a combined Multichannel Analysis Surface Waves (MASW) and Microtremor Method (MAM) methodology using linear array 16 geophones in three selected sites. The allows for comparison dispersion curves generated independently from each technique and, if yield consistent results, development curve that has broader frequency content. In this study, MASW (active) MAM (passive) surveys are compared reliability results is associated to relative orientation...

A bioreactor landfill, where municipal solid waste (MSW) degradation is accelerated by recirculation of liquids, emerges as a promising technology to harvest energy from MSW. Nevertheless, the effect on properties MSW still not well understood. Shear wave velocity (Vs) directly associated with stiffness MSW, but such measurements are rare in landfills. combination multichannel analysis surface waves (MASW) and microtremor method (MAM) has been implemented at six locations Smiths Creek...

Random material is commonly used for building dam embankments. On one hand, random fill materials offer many advantages, such as saving construction cost and reducing environmental impact. the other shear strength of exceedingly difficult to assess. This difficulty mainly associated with large size particles in that inhibit use regular testing equipment. In fact, misinterpretation can lead a catastrophic failure. An in-situ scale direct device 70 cm x 30 was developed testing. has been...

Abstrak. Jembatan Suramadu yang akan menghubungkan kota Surabaya dengan Madura memiliki bentang total sepanjang 5.438 m. Mengingat lokasi pembangunan berada di laut dan beban rencana besar pada tiang pondasi, maka uji pembebanan statik konvensional tidak mungkin untuk dilakukan jembatan utama. Alternatif tes dapat adalah Tes OC mengikuti prosedur Osterberg Cell Test. ini dilengkapi load cell, telltale, strain gauge sehingga diperoleh kurva load-displacement tahanan ujung selimut berbagai...

The feasibility of using an unmanned autonomous aerial vehicle (UAAV) for the performance shear wave velocity measurements is investigated. Proof-of-concept tests UAAV developed at University Michigan were performed two sites, and results are presented. Tests first indoor sand pit facility that was filled with Ottawa to a depth 3.7 m (12 ft). A second test outdoors, stiffer soil site near campus. multichannel analysis surface waves method (MASW) implemented array 16 geophones. Conventional...

A static vertical load cyclic loading...

Basin presence is believed to affect the ground surface response due earthquakes, particularly in areas around basin edge. Previous studies showed that 1-D and 2-D wave propagation analyses resulted significant differences amplification at However, link between responses has not been studied for engineering practices. In practical application, seismic were commonly performed using analysis, example, develop a city micro-zonation map. Based on considerations, it necessary estimate scaling...

Traveler apps for mobile devices such as smartphones are becoming more widely available. This study aimed to identify traveler infectious disease self-monitoring implementation strategies on a application. It analyzed 73 journals from the PubMed database using descriptive-analytic method.

Pile-supported embankments have been recognized as long-standing solutions for construction in compressible soft soils. Instead of improving the physical and mechanical properties soil, this method emphasizes efforts to transfer embankment load a competent layer below layer. Mortar column inclusion (inklusi kolom mortar or IKM) is one rigid inclusions pile-supported embankment. The IKM combined with platform (LTP) has widely utilized support embankments.
