| 摘 要： | 运用系统分析的方法和优势结构面理论,提出了岩土优势结构面的储运水效应的概念,并对它的几个应用方面进行了探讨,结果表明:①岩土体中存在各种类型的结构面,实际岩土工程中的稳定、渗透和突水问题一般是由优势结构面所引起;②在找出优势结构面即富水优势断裂的基础上,确定优势井位、优势井深,可确保缺水地区找水的成功;③地下突水与优势结构面关系密切,但只有具备了多种储运水优势指标的优势结构面才是富水的,才有可能导致突水事故;④在降水和其它地表水的作用下,水将优先向边坡中优势结构面发生渗漏,而水的浸入又加速了土体的软化及结构面的生成,水与结构面相互促进,形成了恶性循环,最后导致滑坡的产生;⑤堤、坝及其地基中的优势面和优势层的存在是内在因素,而水是外在因素。内外因素的联合作用下可能导致堤坝的渗透、变形和破坏。

| Abstract: | Based on the systemic analysis method and the preferred plane theory in roek-soil mass, the concept of storage and movement effect of water on roek-soil preferred structural plane is put forward, and its application is studied. The following conclusions can be drawn. Firstly, there are different kinds of structural planes in roek-soil, and the stability and infiltration problems of roek-soil can be induced by the structural planes. Secondly, after confirming the preferred structural plane, preferred location and preferred depth of well, the finding out of underground water can be ensured. Thirdly, the water emerging in underground engineering has close relation with the structural plane. But only when the structural plane possesses some preferred index, such as time, dimension, it can lead to water-emerging. Finally, the interaction of water and preferred planes can induce the sliding of slope and infiltration destruction of dykes. |
