摘要
本文对岩溶发育区软弱地基、土洞、塌陷岩溶病害及其引起的局部地基沉陷、墙体开裂、危房隐患等,应用单液一步化学硅化法进行地基加固处理原理,主要设备、工艺、灌浆材料的选择、配方、凝胶时间的确定、施工中出现的问题及处理方法等,作了系统的阐述。通过多个工程实例应用化学硅化法的效果分析、阐明该法在岩溶区加固处理地基的可行性及普遍使用意义。
This paper made systematic description for the application of single chemical siliconize method description for the application of the treatment engineering of soft ground, soil cave, karst collapse disease in karst development areas and parts of ground collapse, wall split, hidden trouble of dangerous house, etc. The principle of this method, its main e-quipment, technology, selection of grouting meterial, determination of agglutination time, problems meeting during construction were discussed in this paper. Through the analyses on effectness of this method in many engineering case histories,the feasibility and universal significance of this method used in karst area for foundation improvement had been set forth.
