老挝东泰矿区膨胀性红黏土工程地质特征及评价
Engineering Geological Characteristics and Evaluation of expansive red clay in Dongtai Mining Area,Laos
摘要
Abstract
Expansive red clay is a kind of bad foundation soil,the processing to which is a difficult problem in engineering construction.Taking the reconstruction and expansion project of Dongtai mining area in Laos as an example,through detailed geotechnical engineering reconnaissance,the expansive red clay in the study area has the characteristics of large pore ratio,high fluid limit and high plastic limit.The physical and mechanical properties are poor,it is weak expansion soil,.The foundation expansion and contraction grade is the grade II.Based on the engineering geological characteristics,when the expansion of red clay in the study area is used as the direct bearing layer of shallow foundation,the foundation processing measures such as soil replacement,sand and stone cushion and soil improvement can be adopted;Drainage measures and slope sealing measures shall be adopted for foundation pit works and slope works;and the expansive red clay should be improved in soil and then be used as engineering filler.关键词
