Large-diameter cast-in-place tubular piles offer high efficiency and adaptability for various engineering applications. Despite their widespread use, the bearing behavior of these remains complex due to interactions with internal soil core, related theoretical framework is not yet fully developed. In this study, a simplified load transfer model proposed based on pile–soil interaction mechanism large-diameter piles. Comprehensive models skin friction end resistance both pile body core are...

Redbed soft rocks, widely distributed in China, are highly susceptible to weathering, disintegration, and strength reduction under environmental engineering disturbances, posing critical challenges for slope stability. This study investigates the stability failure mechanisms of high road-cut slopes redbed regions excavation, seismic, rainfall conditions. Numerical simulations were conducted based on actual sites, using FLAC3D finite difference model simulate conditions typical these sites...

The construction industry is the lifeblood of national economy; thereby, to some extent, green transformation representative industrialization levels modern construction, especially in China. Based on panel data A-share listed companies China’s from 2014 2019, this work studies influence mechanism political connection corporate innovation by establishing a multiple regression model, analyzes realization path social responsibility as an mediating variable impact connections innovation, and...

A new application of the internet things in a low-cost greenhouse with no networked intelligent control equipment. The systematic water-saving management focused over whole growth stage crops, and it can effectively increase yield quality. Replace some chemical fertilizer fully-decomposed organic types to reduce negative impact on soil environment. Regarding pesticide usage, we advocate prevention first treatment second. Improve regard decreases crop Abstract . basic is an inexpensive type...

As a new type of bridge foundation, rectangular closed diaphragm walls (RCDWs) provide an efficient solution to controlling the settlement high-speed railway bridges. However, scant research on prediction for RCDWs has hindered their application in practical engineering. This paper attempts establish simplified approach predicting RCDWs. First, analytical model RCDW is established accordance with load transfer approach. Then, curves and related coefficients skin friction foot resistance are...

Geobag retaining wall using construction waste is a new flexible supporting structure, and the usage of to fill geobags can facilitate recycling. In this paper, model tests were performed on geobag waste. The investigation was concentrated slope top settlement, distribution characteristics earth pressures walls horizontal displacements, failure modes. results indicated that ultimate loads tops with could bear 87.5%~125% higher than without walls. loading strengthened slopes different ratios...

Abstract The nodular diaphragm wall (NDW) is a novel foundation that can provide significant uplift load resistance compared to typical foundation. With the advantages of low noise, cost‐effectiveness, high work efficiency, and construction abilities close existing buildings, NDW has excellent engineering application prospects in urbanization construction. However, scarce knowledge on resistance, failure mode, calculation method hindered its practice. In this paper, indoor model tests based...

Rectangular closed diaphragm walls (RCDWs) are often used as bridge foundations because of their advantageous properties such high stiffness and construction efficiency, low cost, minimal vibration noise. However, there is currently a poor understanding the seismic behavior RCDWs in liquefiable deposit, this has limited practical application same. This paper presents results three dynamic centrifuge tests that were conducted to investigate liquefaction mitigation capacities with one two...

Lattice-shaped diaphragm wall (hereafter referring to LSDW) is a new type of bridge foundation, and the relevant investigation on its horizontal behaviors scant. This paper devoted numerical study comparison static seismic responses LSDW pile group under similar material quantity in soft soil. It can be found that bearing capacity considerably larger than group, deformation pattern basically appears an overall toppling while clearly shows local bending during loading process. The...
