复合地层盾构隧道工程地质勘察方法研究

Research on engineering geological exploration method of composite strata shield tunnel

为探究用于复合地层盾构隧道的地质勘探方法,明确现有勘探方法的应用效果,将以实际工程为例进行探究。以遥感勘探技术与地质雷达技术为基础,对以卵石、圆砾母岩为主的地层结构进行探究,通过与工程实际情况进行对比,判断所用方法的准确性与可行性。借助地质勘探数据为盾构工程提供参数参考,以提高盾构施工安全与施工效率。

In order to explore the geological exploration methods for shield tunnels in composite strata and to clarify the application effect of the existing exploration methods, the actual engineering will be taken as an example to explore. Based on remote sensing exploration technology and geological radar technology, the stratigraphic structure dominated by pebble and conglomerate parent rock is explored, and the accuracy and feasibility of the method used are judged by comparing with the actual situation of the project. With the help of geological exploration data, it can provide parameter reference for shield tunnel engineering, so as to improve shield tunnel construction safety and construction efficiency.
