摘要
围护墙结合内支撑系统的支护形式已经在深基坑工程特别是城市中心区域的深基坑工程中得到了广泛应用,但常规的内支撑系统面临着土方开挖困难、施工场地狭小等问题。采用圆环支撑系统结合栈桥的设计可改善土方开挖条件,提高施工效率。通过某基坑工程实例,介绍圆环支撑栈桥系统在复杂环境深基坑工程中的实际应用,为类似工程的支护设计提供参考。
Within the enclosure wall combined bracing system supporting form has been widely applied in deep foundation pit engineering especially in the downtown, but conventional bracing system has problems such as soil excavation difficulties, narrow construction site and so on. The ring support system combining with the trestle bridge design will improve the conditions of earthwork excavation, improve construction efficiency. Through an actual foundation-pit engineering, ring trestle bridge bracing construction system practical application in deep foundation pit engineering in complex environment is introduced, provide a reference for similar engineering design of support.
