摘　　要：在高速公路隧道地质超前预报工作中,充分考虑到隧道围岩的工程地质条件,对隧道围岩初衬后的应力、应变进行数据量测,并分析了围岩压力及围岩位移随时间发展的特征和规律。从分析结果可知,隧道拱脚处围岩压力及位移较小,隧道拱顶附近围岩压力及位移较大,在隧道开挖工作中应对易于出现较大变形的位置加强支护。In the process of geological advanced forecast of tunnel, on the basis of engineering geological conditions of surrounding rock, data of stress and strain of surrounding rock has been tested, and the characteristics and regularity of surrounding rock pressure and displacement has also been studied. By analyzing the results, some conclusions have been obtained： the pressure and displacement in arch foot are less than the pressure and displacement in vault of tunnel. There- fore, more supporting works need to be done in the place with more deformations in the tunnel.

关 键 词：隧道地质超前预报 围岩压力 围岩位移
