摘要
文章对强风化砂岩抗剪强度指标进行了分析和探讨,提出了用岩体结构面抗剪强度指标折减来获得强风化砂岩的内摩擦角和粘聚力的方法,并结合掏挖基础应用条件,通过计算掏挖基础在强风化砂岩地基应用时扩底成型稳定性,得出在强风化泥质粉砂岩和粉砂岩地区掏挖基础在施工过程中能够掏挖成型并大量应用的结论。
The article studies the shear strength of highly weathered sandstone,and proposes to get its internal friction angle and cohesive force by reducing the shear strength in structural plane.Through the calculation of the shape stability in dug foundation based on highly weathered sandstone ground base,it concludes that the dug foundation can be applied to area with highly weathered muddy siltstone and siltstone.
