Abstract: According to recent development of environmental geotechnical engineering, Some characteristics and related disciplines of geotechnical engineering are summarized and elaborated. Environmental geotechnology views and appropriate countermeasures are proposed, and urban construction of environmental geotechnical problems are briefly analysed. By emphasizing potential environmental geotechnology , further development and improvement for theories and pratices can be obtained.

Abstract: We did sorts of shear strength tests in different moisture content conditions with amount of disturbed soil which was collected from the swelling soft rock in the north of xianfeng town open-cast coal. Furthermore, we analyzed the physical relationships between moisture content of the rock-soil mass and shear strength under different soaking time or different moisture content conditions. Finally, we find the shear strength of rock-soil mass drops along with the saturated degree of test specimen doubled and re-doubled. We get a conclusion that soaking of the rock-soil mass has a strong influence on the strength of rock-soil mass. The soaking of groundwater and surface water could soft the rock-soil mass, which plays an important role in controlling the stability of side slope, also in continuing slip deformation.

Abstract: Anti-slide pile deformation of pile retaining wall in expansive soil region was analyzed in this article. Main factor which affected deformation of the anti-slide pile was discussed. The result showed that expansive power and pile embedded solid depth was the main factor which affected the deformation of the pile in expansive soil region. Engineering measure related to the anti-slide pile deformation was alalyzed to show that the anchor cable could effectively controlled the deformation. As well as the order of the anchor cable and slaking effect of expansive soil had a great impact on the pile deformation. It can be used as reference for the design and construction of the pile retaining wall in the expansive soil region in future.
