针对南水北调中线工程河南境内禹州-长葛段总干渠存在的地质问题，如次生黄土湿陷、膨胀岩(土)渠坡变形、煤矿采空区渠道基础稳定、施工降排水等，在渠道工程设计中采取了强(重)夯、土挤密桩、黏性土与改性土换填、抗滑桩、采空区灌浆处理等措施，消除了不良基础对渠道的影响。详细介绍了上述工程处理措施的细节和实施过程，可供类似地质条件的渠道工程设计参考。施工期观测成果表明，该渠段目前处于稳定状态。

Severe geological problems, including loess collapse, expansive soil (rock), stability of coal mined-out area, groundwater drainage in construction, were exposed in canal construction of Yuzhou to Changge section of South to North Water Diversion Project. Aiming at these difficulties, the comprehensive measures were adopted, such as strong tamping, soil compac-tion pile, clay replacement and modified soil filling, anti-slide pile, grouting for mined-out area. The detail treatment meas-ures and construction process are presented, providing references for similar canal construction.
