摘要

因放淤固堤导致河南、山东堤防多处出现纵向裂缝，严重影响了黄河下游标准化堤防工程建设的质量与进度。通过开展现场调研与室内试验，基于饱和-非饱和渗流-应力耦合及湿化变形理论，探讨黄河大堤纵向裂缝的形成原因，据此制定相应的预防与治理对策。研究表明，淤背施工过快是导致大堤开裂的根本原因，堤身湿化变形、淤区排水不畅、堤顶堆载、堤顶重载车辆作用等加剧了堤身裂缝的形成与扩展；控制淤背施工速率、加速淤区排水、避免堤顶堆载等是预防裂缝的有效措施；锥探灌浆、开挖回填等方法可用于治理裂缝。

Abstract

For the Yellow River dikes which are reinforced by desilting

the longitudinal cracks appeared in the standardized dikes in Henan and Shandong provinces in Lower Yellow River; it would effect quality and schedule of project badly. Through in-situ search

indoor experiments and theoretical studies such as saturated-unsaturated seepage-stress coupling

soak deformation

the cracking causes are analyzed; and relevant methods of prevention and curing are carried out. The results show that the construction in high speed is the basic cause of cracks of dikes; and soak deformation of dike

bad drainage of desilting section

stacking load at the tip of dike

impact of vehicle lead to form and develop of cracks. Therefore

the cracks of dikes can be prevented by controlling construction speed of desilting

draining quickly at desilting section

avoiding to stacking load at the tip of dike and so on. Moreover

cracks can be settled with core grouting

cutting and backfilling and so on.
