Clay shale has unique mechanical properties compared to other soil types. When dry and undisturbed, clay will shrink resemble hard rock. the layer exposes air water, it expand experience weathering that causes its shear strength decrease drastically. This research aimed analyze highway construction requires strengthening pile foundation found a of shale. The can be reduced by 20% – 80% when exp...

ABSTRACTThe interaction between pile foundation and soil results a bearing capacity that allows the superstructure to be securely maintained. The impact of structure can lead more accurate analysis, especially on structure's ability endure seismic forces. Therefore, must idealized as multilinear spring support in order analyze structure. Midas GTS NX GEN programs were used examine interactions....

In this paper, based on the actual working conditions of shield tunnel Jinan R3 line through composite stratum, engineering monitoring work was carried out. Combined with GTS/NX finite element calculation software, numerical simulation construction in stratum out, and law ground subsidence caused by obtained, which can provide experience for similar projects, to prevent damage excessive surface...

Abstract For the design of a deep foundation, piles are presumed to transfer axial and lateral loads into ground. However, effects combined generally ignored in engineering practice since there uncertainties precise definition soil–pile interactions. Hence, for technical discussions interactions due dynamic loads, three-dimensional finite element model was developed evaluate soil pile performan...

The issue of interaction between nearby footings is paramount practical significance. interference effect should be taken into account since the footing may really separated from or bounded by other on one both sides. In this regard, paper studies two interfering strip embedded in saturated cohesive soils, which will help to provide a better understanding impact depth effect. A numerical study ...

Introduction . Various calculation methods, including empirical, analytical, and numerical ones, are used to assess the effect of undermining on base deformations force variations in structures existing projected pipelines. Empirical methods typically developed using an experimental analysis numerous results obtained during engineering geodetic observations settlements surface terrain shifts ar...

Abstract. The work reports some numerical tests concerning the use of Embedded Truss elements implemented in Midas FEA NX software modeling a specific FRCM reinforcement system for masonry structures. efficacy finite element is demonstrated through comparison results with experimental obtained by other authors relating both to mechanical characterization materials and response arch models. appe...

By installing FBG sensors on the geogrids, smart geogrids can both reinforce and monitor the stability for geogrid-reinforced slopes. In this paper, a geogrid-reinforced sand slope model test is conducted in the laboratory and fiber Bragg grating (FBG) sensing technology is used to measure the strain distribution of the geogrid. Based on the model test, the performance of the reinforced soil sl...
