摘要为研究硬岩条件下巷道开挖围岩内部位移变化特征，以高放废物地质处置地下实验室北山坑探设施为试验平台，设计原位试验方案，开展围岩内部位移现场量测试验，分析巷道开挖全过程围岩内部位移的演化特征，采用Lee方程、Hoek方程、V-D方程3个典型LDP曲线方程进行掌子面空间效应分析和损失位移求取。研究结果表明：北山花岗岩地质条件下，巷道爆破开挖全过程中，围岩内部位移变化随掌子面的推进呈现初始增长、快速增长和稳定收敛3个阶段；量测断面附近的围岩内部位移时态曲线呈现出阶跃特征，与分级加载下岩石蠕变试验曲线的形态特征相类似；距离巷道侧壁较远的测点受掌子面空间效应的影响范围较小，且在掌子面前方产生的位移释放量所占比重较大；采用Hoek方程求解的损失位移与实测值更为接近，为最优求解方程；在距掌子面2 m远设置量测断面，其损失位移已占总位移的50%以上。研究结果可为后续地下实验室开挖过程中的围岩内部位移量测和分析提供借鉴与参考。

Abstract：The excavation of exploration tunnel at Beishan which is to be the test platform for the underground research laboratory of high-level radioactive waste was investigated in order to study the variation of internal displacement in the hard surrounding rock. An in-situ test scheme was designed and the field measuring of internal displacement in surrounding rock was carried out. The variation of the internal displacement in surrounding rock in the whole process of tunnel excavation was analyzed. The analysis of the spatial effect of tunnel face and the estimation of loss displacement was carried out with 3 typical LDP curves of Lee equation，Hoek equation and V-D equation. The research result shows that the internal displacement of surrounding rock in the whole process of blasting excavation goes through 3 stages，including the initial growth，the rapid growth and the stable convergence. The temporal curve of internal displacement in surrounding rock near the monitoring section shows the step characteristics，which is similar to the morphological characteristics of creep curve of rock in stepped loading test. The measuring points far from the side wall of tunnel is less affected by the spatial effect of the tunnel face and the displacement release in front of the tunnel face accounts for a larger proportion. The loss displacement calculated with the Hoek equation is closest to the measured value. When the measuring section was set 2 m away from the tunnel face，the loss displacement accounts for more than 50% of the total displacement.

Key words： rock mechanics Beishan exploration tunnel whole excavation process internal displacement of surrounding rock loss displacement field measuring test
