Abstract: This paper develops an innovative undrained solution for cylindrical cavity expansion using a hypoplastic model that could well reflect the mechanical properties of clay, especially the structural degradation of unstable ...

Abstract: In this paper, an upper-bound solution for the FCEM is proposed to study the effect of the plastic behavior of soil on the interpretation of a flat dilatometer test. Kinematically admissible displacement fields for the ...

Abstract: This paper proposes an empirical solution to calculate the average ultimate cavity wall pressure (UCWP) of cavity expansion in undrained clay under anisotropic stress through large deformation finite element analysis using ...

Abstract: This paper proposed a theoretical solution for cavity expansion in crushable soils. The constitutive relations of the crushable soils were described by the breakage mechanics model that explains the grain crushing induced ...

Abstract: An experimental study was carried out on the fire-resistant performance of six stainless steel tubular X-joints. The failure process and behavioral responses of all specimens were determined, and the failure criteria of ...

Abstract: The rectangular pipe jacking method, as a new type of shallow tunnel excavation technology, is increasingly widely used in practical engineering due to its advantages of higher space utilization and fewer impacts on the ...

Abstract: This study analyses the classical problem of the ultimate lateral pressure (ULP) of a circular pile in undrained clay considering the undrained strength reduction induced by pile installation. A modified Tresca model ...

Abstract: This paper incorporated two important characteristics of clay, namely its rate-dependent and strain-softening behavior, into a theoretical framework based on cavity expansion. The modified Tresca model for clay proposed ...

Abstract: Urban underground comprehensive pipe galleries (referred to as UCPGs) often have large rectangular cross sections and are now widely used as underground tunnel spaces for accommodating various engineering pipelines used ...
