三峡工程基础化学灌浆设计与应用探讨

通过对丹江口和龙羊峡坝基典型特殊地质问题化灌处理设计与应用的总结分析,并结合三峡工程基础处理设计和现场灌浆试验成果以及已有水泥灌浆施工资料,对化学灌浆处理水工建筑物基础特殊问题的设计与应用问题、三峡工程坝基防渗帷幕和基岩固结灌浆采用化学灌浆的可能性和必要性问题进行了分析与探讨,认为化学灌浆技术在地基加固处理方面有着发展和应用前景,对三峡工程特殊地质缺陷部位,采用化学灌浆进行地基加固问题值得研究.

Design and application of chemical grout to Three Gorges dam foundation

Based on the analyses and conclusions on the design and practice in the typical and special foundation geological treatment at the Danjiangkou and Longyangxia projects, and in combination with the foundation treatment design and the in situ grout test results as well as the operation information about cement grout at the TGP, the design and application of special treatment by chemical grout of the hydraulic structure foundation, and the possibility and necessity of the chemical grout in the foundation impermeability curtain and rock consolidation grout have been analyzed and discussed. It has been believed that it will have good future in the development and application for the chemical grout technology to cope with the foundation defects. It will be worth studying on the foundation treatment by chemical grout of the special foundation defects at the TGP.
