摘要
本文重点研究了未扰动膨胀性岩石的初始含水率与其膨胀势显现强弱的关系和初始干容重与膨胀率之间的关系,并对膨胀性围岩的膨胀变形与支护抗力之间的关系进行了探讨。
This paper emphatically studied the relation between the initial water content of undisturbed swelling rock and its swelling liability and the relation between the initial dry unit weight and swelling, and also investigated the relation between the swelling deformation of swelling rock and support resistance.
