综合物探法在坝体渗漏探测中的应用

Application of Comprehensive Geophysical Exploration Methods in Dam Seepage Detection

摘要:

近年来,随着水库除险加固工作的进行,水库安全、经济效益得到有效保障。但部分水库因施工等因素影响,在除险加固后仍存在渗漏问题,加之近年来我国极端天气频发,小型水库短时间内汇水量骤增,使坝体面临严峻挑战,在短时间内寻找渗漏原因并修复坝体显得迫在眉睫。文章探讨通过物探手段短时间内准确查明渗漏范围及渗径,为类似项目建设提供重要依据。

Abstract:

In recent years, with the implementation of strengthening engineering for endangered reservoirs, the safety and economic benefits of reservoirs have been effective guaranteed. However, due to the negative influence of construction and other factors, some reservoirs still have seepage problems after strengthening. In addition, with the frequent occurrence of extreme weather in China in recent years, the water inflow of small-sized reservoirs has increased sharply in a short time, posing a severe challenge to the dam body. It is extremely urgent to find out the seepage cause and repair the dam body in a short time. This paper accurately identifies the range and diameter of the leakage by geophysical exploration means in a short time, providing an important basis for similar projects construction.
