摘　　要：基坑工程涉及岩土工程、结构工程等,其综合性强、影响因素多。SMW工法围护结构型钢拔出力受多种因素影响。基于对不同粘结长度及不同施工条件下型钢起拔力的实测结果整理,对比分析了不同粘结长度的SMW工法型钢起拔力及其影响因素,认为型钢粘结长度、侧向变形程度、型钢起拔先后顺序等是影响起拔力的重要因素,在工程设计、施工实际中,综合考虑多种因素对型钢起拔力的影响,可较顺利地实现型钢完整回收。Foundation pit is a integrated engineering related to geotechnical engineering and constructional engineering,influenced by many factors.Shaped steel pull-out force of SMW engineering method is influenced by many factors.Pull-out force of SMW engineering method shaped steel of different bonding length and influencing factors were analyzed contrastively,analysis results indicate that bonding length of shaped steel,degree of lateral deformation etc are important influencing factors.Many factors should be considered roundly in engineering design and construction,shaped steel can be pulled out successfully.
