劈裂式灌浆在土坝加固中的应用

Application of split-filling grouting in earth dam reinforcement

劈裂式灌浆主要是解决地下工程隐蔽部位出现的应力集中、地下裂缝、大孔隙颗粒土湿陷、洞穴及密度不够等造成的渗漏和裂缝等病险情况.通过对中卫三眼井病险水库土坝实施劈裂式灌浆,对改善坝体局部应力集中,提高坝体的抗渗性能和增加土体密实度,具有很好的工程效果和推广价值.

split-filling grouting is method that to solve the hidden undergroud project sites that naked eye can not see the stress concentration, under ground cracks, the collapsible porous soil particles, such as caves and not enough density, resulting in works leakag, cracks and other dangerous problems. Through the implementation of dangerous reservoirs dam grouting, the local stress of dam in Zhongwei Sanyanjing has been improved, the dam＇s effectiveness are raised, and the permeakility of soil compaction are increased, the project has a good effect, and has a very widely range of promotion.
