| 摘 要： | 文章以西部某重大工程为例，在详实的调查和试验基础上，研究了冰碛层的水文地质特征及其对工程的影响。研究结果表明：场区冰碛层渗透系数小，透水性微弱，且在垂向上随深度增加，呈逐渐变小趋势；工程条件下，地表水、地下水不会再在场区内冰碛层中形成新的架空块碎石结构，也不会发生渗透破坏，对工程影响微弱。

| Abstract: | This paper focuses on engineering records of a project in a mountainous area in southwestern China. Hydrogeological behavior of a glacial till and its influence on engineering were studied based on filed investigation and laboratory-site testing. Research results show that groundwater is not appropriate for water supply during construction and operation phase. Field runoff and underground water worked together in freezing-thawing cycles which produced cavities in granular moraine layers and has reached a phase of balance. |
