摘　　要：第三系黏土岩作为一种特殊性岩土,具有其独特的工程特性。通过对黏土岩进行室内试验、旁压试验及平板载荷试验,研究了第三系黏土岩的地质特征、物理力学性质,探讨了采用天然地基时,黏土岩作为持力层时的承载力取值问题,提出黏土岩作为天然地基时,可进行一定的深度修正。The tertiary mudstone as a kind of special rock and soil,has its unique engineering characteristics.Based on the geotechnical test,side pressure test and composite plate load test,the engineering geological features and the physical and mechanical properties of the tertiary mudstone are studied in this paper.We also discuss the value of bearing capacity of clay rock as bearing stratum,when clay rock is used as natural foundation,depth correction can be carried out.

关 键 词：黏土岩 室内试验 旁压试验 平板载荷试验
