摘要

在宝泉上水库开挖过程中，环库两岸发育有大小不一的冲沟，虽然冲沟覆盖层主要是可压缩性较小的碎石土，但相对岩质基础，其变形模量仅为千分之一左右，考虑上水库库岸防渗形式(沥青混凝土防渗)，为避免蓄水过程中基础软硬交接面产生过大的不均匀沉降，对其进行正确的分析与评价，是冲沟处理方案需要解决的突出地质问题。

Abstract

Different scales of gulches were found in Baoquan Upper Reservoir during the excavation. The coverages of the gulches are mainly debris soil of less compressibility

but deformation modulus is only about 0.001 compared to rocky foundation. The main issues of the gulch treatment considering the anti-seepage by using asphalt and concrete for of the upper reservoir bank and avoiding large heterogeneous settlement of the contact zone in soft and hard rock

are analyzed and estimated in detail.
