本文首先对软岩矿物成分进行分析，并通过耐崩解试验与室内静态崩解试验，对石林隧道软岩的崩解特性与机理进行分析。研究表明：石林隧道软岩具有极强的崩解性，软岩完全崩解时间随初始含水量的增大呈指数衰减趋势，同时观察发现软岩的崩解过程可划分为崩离、迸裂和解离三个阶段。同时研究得出石林隧道软岩崩解的机理为粘土矿物的膨胀，表面吸附的楔裂以及矿物胶结的弱化。

Firstly, the article analyzes the mineral composition of soft rock mineral , and analyzes the disintegration characteristics and mechanism of soft rock in Shilin Tunnel through disintegration tolerance test and indoor disintegration test.Results show that with a strong disintegration, the fully disintegrated time of soft rock tend to exponential decay along with the increase of initial moisture content .And the disintegration procedure can be divided into three stages as fragmentation, burst and dissociation.Also , the mechanism of disintegration of soft rock in Shilin Tunnel is concluded to be the expansion of the clay minerals, the disjoining of surface adsorption and the weakening of mineral cementation.
