摘要
本文以云南成品油管道工程某站场边坡地层为研究对象,采用室内剪切试验、现场大型原位剪切试验相互对比分析的手段,探讨了不同试验方法条件下岩土体抗剪强度的变化关系,研究了天然和饱和状态下边坡岩土体地层抗剪强度的变化规律,分析对比了全风化白云岩和红黏土地层的抗剪强度变化情况,为边坡设计提供了详实的基础资料,也可为类似边坡地层抗剪强度的获取提供新的思路。
The author use means of comparative analysis between indoor shear test and in-situ large scale shear test to study the slope stratum of the refined oil station of Yunnan refined oil pipeline engineering. The variation of shear strength of rock and soil under different test methods is discussed. The variation law of shear strength of stratum under natural and saturated condition is studied. Comparative analysis of the shear strength of weathered dolomite and red clay layer is implemented. Based on these studies, a copy of detailed information of the slope stratum is provided for the slope designer, and a new way of obtaining the shear strength of the slope stratum is prompted.
