湘中北“红层”岩石地基桩端承载力评价探讨

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。

A DISCUSSION ON THE ASSESSMENT OF THE POINT-BEARING CAPACITY OF THE "RED LAYER" ROCK GROUND AT THE NORTH PART OF MIDDLE HUNAN PROVINCE

Aiming at tl1e problem of the assessment of the pile point- bearing capacity of the "Red layer"ground at the three cities Changsha, Zhuzhou , Xiangtan even the area of the north part of middle Hunan province, on the basis of many years construction practice, by the conparison of various testing methods, this paper concludes that. the calculated design value of pile point-bearing capacity from related code requirements using the testing result of compressive strength at natural water content is comparatively agree with the practice.
