摘　　要：在地质水文条件极为复杂,外部水位反复升降的恶劣环境条件下,短时间内填筑外坡陡峭,沉降变形要求特别高的填方工程,所涉及的技术问题多,无规范可循,难度大。本文以重庆某高填方工程为例,针对复杂环境下高填方工程中存在的技术难点问题,综合运用多种理论和技术,对高填方体的稳定、排水、湿化变形、沉降控制及周围滑坡治理等问题予以解决,可供类似工程参考。During the construction of very tall earth fill with the exterior cragged slope in a short time and especially strict limitation in sedimentation under abominable geological and hydrological condition as well as repeating fluctuation of the outer water level, many technical issues were involved in design and no criterions could be followed, thus the design was very difficult. Aiming at technical difficulties of tall earth fill under complex surroundings, in this paper, taking a project as the example, various theories and techniques are applied synthetically to solve stabilization, drainage, slaking distortion, sedimentatid as reference to the similar projects.
