摘要
南水北调中线总干渠,由于多种因素条件限制必须通过冀豫两省的膨胀土区,工程建设遇到了许多技术难题。笔者的理论分析与现实工程表明,采用换填压胀的措施不是解决膨胀土技术难题的最佳办法。为彻底解决膨胀土影响工程的稳定性难题,应当改变思路,采用规避膨胀土的特性和临空面与优化边坡防护结构相结合的措施,才能使总干渠边坡长治久安,确保工程正常输水。
Restricted by several factors, the main channel in the middle route of the South-to-North Water Diversion Project must go through expansive soil areas in Hebei and Henan provinces so that many technical problems have been encountered. The theoretical analysis and practical engineering show that the expansive soil replacement and compression measures inflation are not the best way to resolve the problems. To solve the impact of expansive soil on construction stability, the meatures that avoid the characteristics of expansive soil and free surface and optimize slope protection should be taken so as to ensure the long-term stability of the main channel slope and guarantee the normal water diversion.
