山西磨河水电站坝基地层多为第四系松散层，主要为混合土漂（卵）石，少量的粉土质砂和低液限粉土，结构松散，分选较差，力学强度低，透水性大。本文针对磨河水电站存在的坝基松散层渗漏、渗透变形、坝基基坑涌水、基岩渗漏和左右坝肩绕坝渗漏等问题，研究提出处理问题的措施和对策，对高山峡谷区坝基处理提供指导性建议。
山西磨河水電站壩基地層多為第四繫鬆散層，主要為混閤土漂（卵）石，少量的粉土質砂和低液限粉土，結構鬆散，分選較差，力學彊度低，透水性大。本文針對磨河水電站存在的壩基鬆散層滲漏、滲透變形、壩基基坑湧水、基巖滲漏和左右壩肩繞壩滲漏等問題，研究提齣處理問題的措施和對策，對高山峽穀區壩基處理提供指導性建議。
