摘要
目前,超深基坑没有统一的认定标准,设计及施工存在着许多难点,一旦出现问题会造成较大的经济损失和安全事故。通过一个具体的工程实例,提出了高喷封底和降水井结合的防渗方案。对超深基坑的设计、施工提出了以施工时间最短为管理目标的建议,并总结了经验和教训,以供类似工程参考。
At present, there is no uniform standard for ultra-deep foundation pit, which has many difficult points in design and construction. Once a problem occurs, serious economic loss and safety accident will be caused. Through an engineering example, high-pressure spraying for sealing and dewatering well are put forward for seepage control. It is recommended to take the in the design and construction of ultra-deep foundation pit, provide reference for the similar engineering. shortest construction time as management objective and the experiences and lessons are summarized toprovide reference for the similar engineering.
