Based on the experimental results and previous studies, the stress ratio at the failure (Mf) under different confining pressures is modified, and the pressure dependency of plastic modulus is discussed. Considering the i...

Artificial assumptions are needed to set the generalized stress paths in hollow cylinder apparatus (HCA). The resulting limitations to imitate the generalized stress paths in HCA are analyzed. According to the function t...

The self-sealing and self-healing behaviors of technological gaps in a high-level radioactive waste repository are analyzed. The systematical findings are summarized based on the previous studies on the effects of techno...

The analytical solutions are presented for the sequential excavation of the tunnel with any shape in viscoelastic rock subjected to anisotropic stress conditions. The complex variable method and the Laplace transformatio...

The earth pressure on rigid retaining wall considering model indeterminacy is focused. Based on the force equilibrium equations for sliding mass, the functional extreme-value isoperimetric model for earth pressure in the...

The experimental tests are carried out on the strength and deformation characteristics of four typical rock samples of phyllite taken from the northern tunnels of Longmen Mountains of the Chengdou-Lanzhou Railway. The re...

Due to the viscosity and easy-cracked characteristics of clay, series problems, such as non-homogeneity, low-saturation and microcracks, exist in the hollow cylinder specimens generally made by using the compaction metho...

The property of the soil in free field is an important influencing factor for the free field seismic response. In the existing studies the soil at local site is supposed to be the single-phase medium or saturated porous ...

The voids behind the tunnel linings seriously affect the interaction between the linings and the surrounding soils, generally in the form of cracking, spalling or even failure, directly affecting the safety of tunnel ope...

The impact roller (IR) compaction method is an efficient and cost-effective compaction technique, which has been widely used in highway and airport engineering for subgrade compaction and ground improvement of soft found...

The right line tunnel is leaked and the segments are damaged due to an accident happening to TBM tunneling on running section in a city. The general situations of the project, the accident process and the emergency measu...

Through the field vane strengths SuFV of 19 projects involving two sedimentary facies of coastal plain and lacustrine plain in Shanghai and combined with the worldwide research findings, the overconsolidation ratio (OCR)...

The statistics of uncertain rock and soil parameters can be updated with the information from different sources such as in-situ measurements and field observations via probabilistic back analysis, which can be further us...

A series of CU triaxial tests on clay reinforced by basalt fiber are performed under controlled soil dry density conditions, and the ratio of basalt fiber content to dry soil by weight is 0.0%, 0.1%, 0.2%, 0.3% and 0.4%....
