Pre Treatment Technology for Karst Caves in Shield Tunnel Crossing Areas
Our country has a vast territory,and the road traffic network is spread all over various areas,which inevitably will carry out underground tunnel drilling,which makes the shield tunnel technology has become one of the indispensable construction technologies in the construction of urban underground engineering.With the continu-ous expansion of tunnel engineering,China's shield tunnel technology has been relatively mature,but because its engineering is greatly influenced by geology,when passing through complex geological environment such as strong karst development,it will still face construction risks and obstacles.Therefore,this paper starts with the significance of pre-treatment technology of shield tunnel through karst cave area,and discusses the concrete construction steps of pre-treatment technology such as geological exploration,karst cave treatment,and stability assessment.Through the implementation of comprehensive geological exploration,accurate cave filling,and strict quality control,the shield tunnel project provides a complete set of cave pretreatment scheme to ensure the safety,reliability and econ-omy of the project,and also provides a reference and prospect for the future development of tunnel engineering.
