综合物探技术在果子沟隧道勘察中的应用

Application of Integrated Geophysical Exploration Technology in Guozigao Tunnel Survey

在长输管道工程中,对于覆盖层厚度变化大、构造发育的山岭隧道的勘察,综合运用瞬态瑞利面波法、高密度电阻率法、直流电测深法和二维反射波地震勘探等物探手段可以提高资料的解释精度和成果的可靠性。果子沟隧道的勘察结果表明,综合物探方法在解决横向和竖向变化的地质问题(物性差异)时有明显的优越性,而且具有方便、经济、快捷和成果直观等特点。

In the tunnel survey of long-distance pipeline project in the mountainous area with great coverage variation in thickness and tectonic development, application of integrated geophysical exploration technology including transient Rayleigh surface wave, high density resistivity method, direct current depth detection method and 2D seismic reflection wave method can increase information analytic accuracy and result reliability. The survey results of Guozigou tunnel show that the integrated geophysical exploration technology has the predominance in solving the problems of vertically and transversely variational geological properties, and has the advantages such as being convenient, economical, quick and intuitionistic.
