摘要
针对在广州市轨道交通四号线某盾构工程中所遇到的浆液流失、管片上浮等问题,通过开展砂浆配合比试验研究,找到了能满足施工需要的配合比。在此基础上,对几种主要材料的特性进行总结,为今后类似工程施工提供了参考。
Based on the problems such as the losing of cement mortar and segment upward moving of the shield tunneling of Guangzhou No. 4 metro line the research test has been done to find the proportioning which well fit the needs of shield tunneling. And the main materials characters in cement mortar are summarized which may provide reference for similar projects.
