摘要

研究目的:作者通过对东莞 R2 线花岗岩类残积土物理力学指标统计分析，找出花岗岩类残积土的物理力学特征，建立物理指标与力学指标之间的关系，提出花岗岩类残积土工程勘察的措施及建议。

研究结论:( 1) 东莞市花岗岩类残积土颗粒成分呈现“两头大，中间小”的特点，天然孔隙比较大，液性指数较小，抗剪强度较高，压缩系数偏大，压缩模量偏小，膨胀性小等; ( 2) 天然孔隙比与压缩模量之间存在一个线性关系; ( 3) 勘察宜采用现场原位测试与室内试验相结合的综合方法

Abstract

Research purposes: By the statistic analysis of the physical and mechanics indexes of the granitoid residual soil Line R2 in Dongguan，the physical and mechanical properties of the granitoid residual soil are found out，the relation between the physical and mechanical indexes is set up and some measures and recommendations on the engineering in granitoid residual soil area are offered．

Research conclusions: ( 1) The particle composition of the granitoid residual soil in dongguan has features of big ends， small middle part，big natural pore，small liquidity index，strong shear strength，big compressive coefficient，small compressive modulus and small the expansive property． ( 2) There is a lineal relation between the natural pore and the compressive modulus． ( 3) The in － situ test should be used along with the indoor test for the investigation．
