Study of Safe Distance Criterion between Concealed Karst Cave and Tunnel Yongbiao Lai 1,2, a, Mengshu Wang 1,b and Xinhua You 2,c 1 College of Civil Architecture and Engineering, Beijing Jiaotong University, Beijing 100044, China 2 China State Construction Engineering Corporation Technical Center, Beijing 101300, China alyb3258@126.com, bdxgc@sina.com, c 78717715@qq.com Keywords: Concealed Karst Cave, Tunnel, Safe Distance Criterion, Energy Catastrophe.
For currently engineering design between concealed karst cave and tunnel is often half experience based on the previous engineering experience and giving a bigger safety stock, many engineering example, seldom theoretical research.
According to energy catastrophe criterion , the safe distance of this engineering example is 9.5 m, part of the calculation results are shown in table1 [8].
According to safety coefficient catastrophe criterion, the safe distance of this engineering example is 10 m [8].
In addition, numerical difference of the calculation results based on three safe distance criterion is not more than 1m,which show can satisfy the engineering practice requirements.

The temple constitutes one of the most famous ancient temples dedicated to Apollon, built in (420-410 BC) by Iktinos, the same civil engineer who previously created Parthenon.
