摘要
在深圳公明地区的16个勘察区域进行了十字板剪切试验和静力触探试验,分析了典型地基土的原位不排水强度与静力触探锥尖阻力间的关系并归纳出公式。利用经验公式将静力触探测试的锥尖阻力成果转化为原位土体的不排水抗剪强度指标,用于分析深圳公明水库土石坝软基抗滑的稳定性,反映了坝基土的非均质性以及地质缺陷对坝坡稳定的影响。
Both the vane shear test and cone penetration test are carried out within 16 investigating regions in Gongming District of Shenzhen; from which the relationship between the in situ undrained shear strength and the cone point resistance of the cone penetration test for the typical foundation soil is analyzed and the relevant expressions are given. Based on empirical formula, the result of the point resistance of the cone penetration test is converted into the index of the undrained shear strength of the in-situ soil and then used to analyze the anti-slide stability of the soft foundation for the embankment dam of Gongming Reservoir in Shenzhen ; by which the impacts from both the non-homogeneity of the foundation soil and the geological defects concerned on the dam slope are also reflected.
