摘要

目前国内正在修建或拟修建大量海底隧道，其中最小岩石覆盖厚度直接制约着海底隧道的造价。根据已确定某海底隧道最小岩石覆盖厚度，结合海底隧道所处的工程地质和水文地质条件，分析了裂隙岩体的断裂损伤、海水渗流和施工过程及爆破、地震等对海底隧道最小岩石覆盖厚度的影响分析。结合工程类比法和数值计算方法得到某海底隧道最小岩石覆盖厚度，考虑各种因素对最小岩石覆盖厚度的影响，最终分析出较优的最小岩石覆盖厚度。

Abstract

At present

many subsea tunnels are under construction construction or to be constructed in China. Their costs are directly restricted by the minimum rock covers. Under the condition of the minimum rock covers

by applying fracture-damage

seepage and construction process model

the minimum rock covers are analyzed with the engineering geology and the water conditions of the subsea tunnel. At the same time

the minimum rock covers are affected by earthquake and blasting etc. Finally

by using project analogy method and numerical method and considering different kinds of factors effecting minimum rock covers

a better minimum rock cover can be chtained.
