摘要
依托广州市轨道交通沿线岩溶地质环境及处理专题研究,从骨料与胶结物的配比、胶结物中各胶结材料的掺量、水灰比对试块强度的影响等三个方面进行研究,采用正交试验法得到了模拟原岩的相似材料及其配比。并对以水泥、明矾为胶结材料的相似材料进行了初步的试验研究,为今后的研究提供了一定的参考依据。
Depending on the study of Karst geo-environment and treatment along urban train transit in Guangzhou, the similar materials and their mixture ratio simulated original rock are obtained by the orthogonal experimental design from the following aspects：① the mixture ratio between aggregate and cement; ②volume of cement materials; ③influence of sampling strength by water cement ratio. Then the preliminary test of similar materials is studied, in which cement and alum are cement materials. It is provided for the future study as a reference.
