摘　　要：在某电缆隧道施工过程中,当竖井通过软弱夹层时,竖井井筒受到地压作用而发生破坏,影响施工进度。为解决这一问题,对此竖井地压问题进行力学分析,通过隧道地压与竖井地压的力学分析计算,得出了软弱夹层的极限埋藏条件与井筒的侧向压力。When the shaft passes through the soft interlayer in a cable tunnel engineering, the pit shaft is destroyed by virtue of the ground pressure and the progress of the engineering is limited. In order to solve this problem we make a mechanical analysis on the ground pressure of this shaft. By mechanically analyzing and computing the ground pressure of the tunnel and shaft, the limit embedding condition of the soft interlayer, and its side pressure are obtained.

关 键 词：地应力 软弱夹层 极限埋藏条件 侧压 地压
