摘要

通过地质调查及大量岩土力学试验，对巴东新城区中三叠统巴东组二段T2b2紫红色泥岩工程地质性质进行了综合研究。测定了岩石的矿物成分及微观结构和岩石的物理及水理性质参数。由不同含水状态下的室内崩解试验发现，紫红色泥岩具有较强的崩解特性，且与岩石的物理状态密切相关，试验得到岩块的力学性质指标和变形特征。进行了点荷载试验，对不同风化程度和不同物理状态下的岩石的工程地质性质进行了分析，并指出其对工程的影响。

Abstract

Based on geological investigation and rock and soil experiments

the engineering geological characters of aubergine mudstone (T2b2) is studied synthetically. The mineral component and microstructure of the mudstone are determined. The physical and water-physical parameter of the mudstone is tested. Based on the disintegration test under different water contents

the stronger disintegration character of the mudstone is observed. The disintegration is nearly related to the physical state of rock. With the indoor test

the mechanical parameters and deformation character of the rock mass are obtained. With the point load test of the mudstone under different weathering degrees and different physical states

the engineering geological characters of mudstones with different weathering degrees and the influence on engineering construction are analyzed.
