本文对长沙，株洲、湘潭三城市乃至湘中北地区“红层”地基桩端承载力评价的问题，在多年施工实践的基础上，通过多种试验方法的对比，得出天然湿度抗压强度试验成果按有关规范要求计算桩端承载力设计值比较符合实际的结论。 This paper evaluates the bearing capacity of the “red layer” foundation in the three cities of Changsha, Zhuzhou and Xiangtan, and even in the central and northern parts of Hunan. Based on the practice of many years, the comparison of various test methods has yielded the compressive strength of natural moisture. The test results calculated according to the relevant specifications require that the design value of the bearing capacity of the pile end meet the actual conclusion.
