摘　　要：我国西部水电等基础设施建设当中面临大量的岩质地基工程,该地区复杂的地壳构造运动和岩体变形使得岩质地基工程中常常分布有断层构造,形成了断层地基。断层地基上修建建筑物或构筑物时需根据断层的成因、产状、岩性等特征及建造对象的使用功能、结构形式、作用荷载等分别采取处理措施进行加固治理。处理的原则是明开挖、少扰动、强度高、接触好、防渗强、畅排水。处理措施一般包括填塞、架拱、衬洞、沉井、支撑(柱、框架、桩)、设墙、锚固等。The faults produced by the deformation and motion of Earth's crust are distributed on the geotechnical foundation engineering.The fault foundation includes the upper rock mass,lower rock mass and the structure surface.It is necessary that the properties of rock mass,structural surface,deposit history,and structure function are considered in design of building.The principles of design and construction are excavation from ground,non-disturbing,increasing strength,anti-seepage and draining freely.The fault is reinforced by some effective measures including filling,arching,lining,settling well,supporting with column and pile,anchor and so on.
