摘　　要：随时监控量测技术能够快速准确地量测隧道整个断面的变形情况,及时掌握监控围岩的稳定状态,较好地预测现场围岩的变化情况。主要介绍深圳葵坝路隧道施工过程的监测方法,并对监测数据进行回归分析。实践证明,该方法可较准确地预测围岩的最终变形量,评判围岩等级及支护结构的稳定性。The at-any-time monitoring and measuring technology can quickly and exactly measure the de- formation circumstances of the whole tunnel section, timely grasps the stability status of the monitored sur- rounding rocks and preferably predicts the deformation＇ circumstances of on-site surrounding rocks. The paper mainly introduces the method of monitoring the construction process of Kuiba Road Tunnel in Shen- zhen and makes regression analysis of monitoring data. The practice proves that this method can make a fairly exact prediction on the final deformation volume of surrounding rock, judge the surrounding rock grade and the stability of the supporting structure.
