%X 公路隧道在工程建设中愈发常见。为研究裂隙围岩在开挖扰动作用下的塌方规律，本文以某一公路隧道为工程背景，借助UDEC离散元模拟软件，得到岩体位移、速度、加速度随时间变化的曲线图，模拟开挖扰动下隧道塌方的演变过程，为类似的隧道工程建设和支护提供建议。<br />
Highway tunnels have becoming more and more common in engineering construction. To study collapse law of fracture surrounding rock under excavation disturbance, based on a highway tunnel engineering, this paper carries out numerical simulation of the evolution process of tunnel collapse by virtue of distinct element method software UDEC and get the rock mass displacement, velocity and acceleration changing curve with time, thus providing suggestions for the similar tunnel engineering construction.
