摘要
以广华新城小区配套学校项目深基坑开挖为背景,介绍多桩型组合支护体系在复杂地层环境下的施工特点、成桩技术。通过进场施工勘察、基坑支护深化设计,并根据不同地质条件合理设置适宜的基坑支护形式,从而满足土方开挖需求,保证基坑支护安全,为类似工程实践积累了参考经验。
Taking the excavation of deep foundation pit of a supporting school project in Guanghua new town community as the background,this paper introduces the construction characteristics and pile forming technology of multi pile combined support system in complex stratum environment.Through the on-site construction investigation,deep design of foundation pit support,and according to different geological conditions,the appropriate foundation pit support form is reasonably determined,so as to meet the needs of earthwork excavation,ensure the safety of foundation pit support,and accumulate reference experience for similar engineering practice.
