摘要
以长沙某商住楼基坑支护加固为例,分析了基坑壁失稳的原因,在综合考虑多方因素后,就不同程度失稳的基坑壁提出并实施分段不同的支护加固方案,得到了较好的支护效果。
Taking for example the foundation pit support reinforcement of a commercial/residential complex in Changsha, the causes for stability loss of the foundation pit were analyzed, after considering many factors, different support reinforcement schemes were put forward for the foundation pit walls that had different degree of unstability, and good support effect was obtained.
