在对旧隧道病害的诊治过程中,综合物探勘查以其多快好省的特点,显示出无比的优越性。用探地雷达可检测混凝土衬砌层质量和衬砌层后背的脱空情况;以高密度电法为主,结合地震折射波法,可查明断裂构造的分布情况;地震折射波法辅以高密度电法,可对围岩进行分级。给实际工程可起到示范作用。 During the diagnosis and treatment of the diseases of the old tunnels, the comprehensive geophysical survey shows the superiority of the geophysical exploration in terms of its characteristics of being quicker and cheaper. Ground penetrating radar can be used to detect the quality of concrete lining and the emptying of the back of the lining. The high-density electrical method is the main method. Combined with the seismic refraction wave method, the distribution of fault structure can be ascertained. The seismic refraction wave method is supplemented with high Density electricity method, can carry on grading to the surrounding rock. To the actual project can play an exemplary role.
