Abstract: Masonry dams' leaching-corrosion is one of popular causes that threaten dam stability and safety. Leaching-corrosion directly decreases material strength, increase the porosity and aggravate dam leakage. In this paper, leaching-corrosion of a masonry dam, located in Guangdong province, is studied. To provide scientific basic for leaching corrosion treatment, geophysical exploration, drilling exploration and detection are used, combining with seepage numerical simulation and analysis. Meanwhile, damage to the dam is decreased maximally in the procedure.

Key words: masonry dam, leaching-corrosion, leakage

摘要： 浆砌石坝的溶蚀会直接导致材料强度降低、孔隙率增大、坝体渗漏加重，对大坝的稳定和安全构成很大威胁。通过对广东省某水库浆砌石坝的溶蚀问题进行研究，运用物探、钻探、检测方法，结合渗流数值模拟计算分析，探讨砂浆的溶蚀问题，为浆砌石坝溶蚀问题的治理提供科学的依据。在研究过程中最大限度降低研究对坝体的破坏。
