摘要
结合隧道渗漏试验结果与地下水渗流过程中能量关系的分析,对影响地下水渗流水压的因素进行了探讨;联系工程实际与渗流过程的能量关系,提出了降低排水型隧道衬砌承受渗流水压的"分步折减"的思路。
The influencing factors of seepage-induced water pressure were discussed based upon the result of seepage tests in one tunnel model and the analysis of energy relationship during the seepage process.Subsequently the thought of "two-stage reduction method"was brought forward on how to reduce the water pressure acting on the lining of drained tunnel.
