摘要
根据某超深基坑周边环境复杂的实际情况,在综合考虑多方面因素后,设计采用了加长土钉并对其施加预紧力的土钉墙支护加固方案,不但降低了工程造价,并保证了基坑支护系统的安全可靠性。
Based on the complicated circumstances around the extra deep foundation pit,and after comprehensive consideration of many factors,the new method of soil nailing wall support scheme was adopted.In this scheme,the soil nail was lengthened,and pre-stress was given.Therefore the engineering cost was lowered and the security and reliability of the foundation pit supporting was guaranteed.
