为了保证土压平衡盾构区间基岩经爆破处理和封闭注浆后的地层的气密性，采用高密度电阻率法与面波地震法相结合的方法，对隧道范围内的基岩爆破和注浆处理效果的物探检验技术进行研究。主要研究成果如下：1）在一定程度上实现了定量分析，将爆破和注浆施工质量具体地反映在电阻率值和横波速度数值上。2）实现了对爆破和注浆施工质量的连续监测和最终检验评价，对爆破和注浆施工有一定的指导作用。

Bed rocks intrude into the seope of a shield-bored running tunnel of Shenzhen Metro. Blasting and grouting are carried out so as to ensure the successful driving of the shield. Geophysical prospecting, including high density resis- tivity method and Rayleigh wave method, is made to detect the effect of the blasting and grouting. In the paper, study is made on the mentioned geophysical prospecting methods. Conclusions drawn are as follows: 1 ) Quantitative analysis is achieved to some extent and the effects of the blasting and grouting are reflected by the resistivity and the transverse wave velocity. 2) Continuous monitoring and final evaluation of the effects of blasting and grouting are realized, which can provide reference for the blasting and grouting.
