There are many drawbacks in traditional loess-strengthening technology. MICP (microbially induced calcium carbonate precipitation) technology provides a new approach to loess management, but there few studies on solidification and lack of engineering application research verification. This study investigated the strength microscopic mechanisms solidified by combined with plant straw. The permeability conditions for were derived, multiple sets experiments conducted using specific loess,...
Combined with the soft clay layer of Foshan metro, a back‐analysis method combining model test and numerical simulation is developed. First, similitude criterion for used in this study was derived from similarity theory elasticity mechanics equations. Artificial prepared by mixing kaolin, bentonite, loess, river sand proportions 4 : 2: 3 1. Gypsum, water, borax are mixed 1 0.7 0.015 to simulate tunnel lining. The tests were carried out based on four load modes: combination mode 1, vertical...
Through three stress path tests of unsaturated Ili undisturbed loess, the effect soluble salt content on deformation net mean stress, suction, and deviated were investigated. The mechanical properties normalized compression curve, soil water characteristic curve critical state line revealed. test results indicate that: in isotropic test, normal curves controlling different suctions can be characterized by using initial void ratio yield described as a two-parameter exponential function. In...
In order to study the variation law of support pressure and instability mode excavation face under different soil parameters, a complete set centrifugal model seepage test device is independently developed. The results tests with C / D (where overburden thickness tunnel diameter), internal friction angles, heights water head show that increase retreating displacement S surface, P surface can be divided into three stages: rapid decline ( < 1.5 %), slow rebound after reaching limit lim...
In practical engineering, if the influence of noncoaxial stress and strain is not considered, part soil deformation will be ignored, resulting in structural design which safe enough. A series undrained tests was performed on remolded loess specimens using a hollow cylinder apparatus to examine coupling between principal magnitude direction these specimens. First, elastic parameters were obtained, used as basis for investigating noncoaxiality body under axis rotation (PSAR). The effects...
