［摘要］深大基坑、地下洞隧等地下工程越來越多，安全管理和風(fēng)險(xiǎn)管理日益得到重視，但是由于種種原因，地下工程事故仍不可避免。對(duì)于工程事故，應(yīng)開展巖土工程司法鑒定，不僅可以對(duì)于事故原因進(jìn)行全面和深入的調(diào)查，而且有利于巖土工程技術(shù)總結(jié)。本文通過對(duì)于北京兩則地下工程事故的巖土工程司法鑒定，總結(jié)出如下事故原因：工程地質(zhì)條件復(fù)雜、設(shè)計(jì)方案不盡合理、周圍復(fù)雜環(huán)境的影響、專家論證不是上保險(xiǎn)，并為安全管理提出如下地下工程設(shè)計(jì)和施工中的一些預(yù)防與注意事項(xiàng)：地層的突變性、工程周邊環(huán)境、計(jì)算參數(shù)的合理取值、時(shí)刻關(guān)注地下水。

Abstract: The safety accidents have also occurred often with underground projects of deep foundation excavation and underground tunnel are more and more. The underground engineering accidents are inevitable in Beijing area in the strict control of the design, construction and management. Some collapse accident of typical open-cut and tunneling engineering appeared. Through the analysis of the accidents, summed up as follows: complicated engineering geological conditions, design reasonable, the influence of complicated surrounding environment, expert argumentation is not insurance. Some preventive and matters needing attention of underground engineering design and construction are put forward: formation of the mutant, engineering environment, reasonable values of parameters, pay more attention to groundwater all the time.

Keywords: underground engineering; failure; forensic geotechnical engineering
