水文地质勘察中压水试验方法及存在的问题研究

Study on Test Method and Existing Problems of Pressurized Water in Hydrogeological Survey

渗透性对于保障建设工程的安全至关重要,压水试验是对基岩渗透性进行分析的常用手段。本文分别对吕荣压水试验法、三段压水试验法、交叉孔压水试验法等三种现场压水试验法作了介绍,并分析不同方法中存在的不足之处,同时就吕荣压水试验法工程实践中经常遇到的问题进行了总结及分析。

Permeability is very important to ensure the safety of construction projects.Pressure water test is a common method to analyze the permeability of bedrock.This article introduces three types of on-site water pressure test methods,such as Lu Rong pressure water test method,three-stage pressure water test method,and cross-hole pressure water test method,and analyzes the shortcomings of different methods.The problems often encountered in the engineering practice of the pressure water test method are summarized and analyzed.
