摘要
通过对地铁管片生产常见问题逐步分析,结合管片表面龟裂产生原因,探讨了水泥用量及用水量等影响混凝土收缩的主要因素,同时总结了解决管片表面龟裂的思路和措施,为今后管片生产提供了参考。
Through analyzing subway segment problems,combining with segment surface crazing causes,the paper explores the impact of cement amount and water amount upon concrete shrinkage,and summarizes concepts and measures of solving segment crazing,which has provided some reference for segment production in future.
