| 摘 要： | 针对东莞轨道交通花岗闪长岩残积土及全强风化岩的崩解特性,结合崩解试验和颗粒分析,得出其具有崩解性和产生的原因,以及岩(土)体由慢速崩解到快速崩解再到慢速崩解的三个阶段;崩解性与岩石失水程度有关:失水越多,失水过程越剧烈,崩解量越大,速度越快;从残积层、全风化层和强风化层的崩解速度和崩解量中看出,随着风化程度的减弱,崩解性有所减弱。

| Abstract: | According to the disintegration properties of granodiorite residual soil and completely strong weathered rock in Dongguan Rail Transit,combined with disintegration test and particle analysis,it is concluded that they are easy to be disintegrated and the causes of disintegration are obtained.Rock(soil) mass is disintegrated through three stages from slowly to rapidly and then to slowly.Disintegration property is related to the degree of water loss,which means that the more water loss and more severe process ... |
