摘要

高摩赞坝基岩体主要为侏罗系薄层灰岩夹砂质页岩,受区域多期构造运动影响,岩体中结构面发育,坝基岩体具有岩石强度高、岩体模量低的特点。为满足建造混凝土坝的要求,施工过程中对坝基岩体进行了多期加固处理。通过加固处理前后坝基岩体质量的对比研究,分析加固处理效果,为其它类似工程提供参考。
        The dam foundation rock mass of Gomal Zam Dam mainly consists of Jurassic thin- layer limestone with an interlayer of sandy shale.Structural plane is greatly developed in the rock mass since it suffered from several regional tectonic movements.The rock mass has the properties of high strength and low deformation modulus.In order to meet the need of the concrete dam,the dam foundation rock mass is reinforced by stages in the process of construction.This study can provide some guidance for projects with similar conditions by comparative study of rock mass quality after and before reinforcing treatment and analysis of reinforcing effect.
