东华理工大学毕业设计（论文） 摘要 摘 要 本文根据常州市凯悦中心二期三号楼岩土工程勘察资料，运用工程地质钻探，原位测试，室内试验等方法，在系统介绍场地工程地质和地基土的物理力学指标统计参数的基础上，对拟建筑场地岩土工程进行分析与评价，给出了各土层的承载力特征值，选择出了适合的持力层，并给出了地基土承载力、地基土容许承载力及桩基设计参数、基坑支护设计参数。其中桩径为0.5m，桩长25m，进入持力层8A的承载力容许值为2500kN，进入持力层8B的承载力容许值为2600kN。综合评价认为该场地无特殊不良地质现象，场地稳定性良好，适宜作为建筑场地。 关键词：高层建筑; 基坑; 工程地质条件; 治理措施 东华理工大学毕业设计（论文） ABSTRACT ABSTRACT according to the geotechnical engineering investigation materials on Changzhou Kaiyue center 2, no.3 building,applying engineering geological drilling, in-situ test, laboratory test methods, on the basis of systematically introducing engineering geological conditions of site and the physical and mechanical index statistical parameters of foundation soil, the paper analysed and evaluated geotechnical engineering of the construction site, gave the bearing capacity of every stratigraphy, selected the applicable bearing stratum, and also gave the bearing capacity of the foundation soil, the allowable bearing capacity of the foundation soil,the parameters of design for pile foundation and foundation pit support. In this exploration, the pile φ0.5m, length 25m, entering into the bearing stratum of subsoil 8A, its allowable value of bearing capacity was 2500kN; entering into the bearing stratum of subsiol 8B, its allowable value of bearing capacity was 2600kN。 The comprehensive assessment showed that there is no adverse effects of bad geological phenomena and geological disasters. The site stability of the proposed site is good, suitable for construction sites.
