综合测试方法在黄登水电站工程大坝灌浆效果检测中应用

Application of Comprehensive Test Method in Grouting Effect at Huangdeng Hydropower Station Dam Project

坝基岩体灌浆效果的好坏直接影响到岩体的整体质量,在灌浆前和灌浆后采用多种综合的测试手段和方法对岩体进行检测,可提供灌前岩层裂隙的发育情况,为指导施工及变更设计方案提供科学依据,在灌后可根据综合检测成果来客观评价灌浆效果,为施工质量提供有利保障。

The effect of grouting for the dam foundation rock could influence the overall quality of the rock. The inspection of the rock before and after grouting by comprehensive measurement techniques shows the crack development in the rock before grouting. It could provide the guidance for con-struction and the design proposal modification. It also could judge the effect of grouting based on the comprehensive measurement at the after-grouting stage.
