摘　　要：通过根石探测,了解撑握对渭河下游河道险工与控导工程安全具有重要影响的根石基本情况,对及时补充根石、加固维护工程安全、发挥工程效用具有重要的意义;本研究对人工锥杆探测、水下浅地层剖面勘探根石两种根石探测方法在渭河下游的实践进行对比分析,指出人工锥杆探测根石存在的主要问题与成果准确性低的原因,以及两种技术适用范围、探测效率、成果精度、安全性与运行费用等方面的优劣,提出水下浅地层剖面勘探根石在渭河下游基本适用,应适度引进、运用与发展,对今后渭河下游开展与提高根石探测工作水平具有重要的指导作用。It is of great significance to understand and maintain the basic situation of the root and stone and to control the safety of the project in the lower reaches of Weihe River. Through the comparison of the artificial pyramid exploration and the underwater shallow stratigraphic exploration, two kinds of root and stone exploration methods in the lower reaches of the Weihe River are compared and analyzed. It is pointed out that the accuracy of the experimental results is difficult to guarantee and the labor intensity is high. Through comparison of the two technologies＇ suitable scope, the exploration effect, the result accuracy, the satety and the working cost and etc., their superiority-inferiority show that the underwater shallow stratigraphic exploration is available here and suggested that it can be introduced at some extent, and it can help to improve the development of the the lower reaches of the Weihe River and also improve the level of detection of the root stone.
