摘要:
以恩施地区广泛分布的红砂岩细粒土为例,通过室内试验,对比分析了5种典型红砂岩细粒土在天然密度、天然含水量、颗粒级配、最优含水量及抗剪强度等物理、力学特性方面的差异,并探讨了物理性质参数与力学性质参数的内在联系. 结合工程实例,通过数值模拟方法获得不同红砂岩细粒土作为填料时路基的沉降特性,探讨了产生沉降差异的原因. 结果表明:上述红砂岩细粒土的物理、力学性质有差别,作为填料时路基的沉降量有显著差异,建议施工过程中选取土料时加以区分.
Abstract:
Taking red sandstone fine-grained soil widespread in Enshi,Hubei province as a case, both the physical and mechanical properties of five typical red sandstone fine grained soil,including natural density,natural water content,particle size distribution,optimum water content and shear strength were comparatively analyzed by laboratory tests,and the inner relationship between the physical and mechanical property parameters was also discussed. Combined with engineering cases,we explored the settlement characteristics of roadbed filled by the five red sandstone fine-grained soil,and the cause that leads to different settlement. The results show that the settlement of the roadbed may be significantly different when the red sandstone fine-grained soil is used as the filler. It is recommended that we should distinguish the soil material in the construction process.
