Comprehensive treatment method for preventing bottom heave instability of deep soft foundation dumping site
The invention discloses a comprehensive treatment method for preventing bottom heave instability of a deep soft foundation dumping site. The method is characterized in that a gravel pile vertical-horizontal consolidation drainage system and a layered preloading and reverse pressing system are adopted to carry out comprehensive treatment on a deep soft foundation; the gravel pile vertical-horizontal consolidation drainage system is composed of gravel piles (3), geotechnical cloth (2) and a gravel cushion layer (1); and the layered preloading and reverse pressing system is positioned at the upper portion of the deep soft foundation gravel pile vertical-horizontal consolidation drainage system and adopts large stones, gravels and/or broken stone materials to carry out graded preloading. According to the method, the technical problem that the bottom heave instability of the dumping site exists when dumping is carried out at the deep soft foundation of the slope toe of the dumping site is solved, the space of the scoured soft foundation area at the downstream of the dumping site can be effectively utilized, the dumping volume of the dumping site can be greatly increased, the whole stability of the dumping site can be significantly improved, and necessary preconditions are provided for capacity expansion of the dumping site.
本发明公开了一种防止深厚软基排土场底鼓失稳的综合处理方法，采用碎石桩竖向－水平固结排水系统、分层堆载预压和反压系统对深厚软基进行综合处理，所述的碎石桩竖向－水平固结排水系统是由碎石桩(3)、土工布(2)、碎石垫层(1)共同构成；所述的分层堆载预压和反压系统位于深厚软基碎石桩竖向－水平固结排水系统的上部，采用大块石、砾石和/或碎石物料进行分级堆压加载。本发明方法解决了在排土场坡脚处深厚软基处进行排土存在的排土场底鼓失稳技术难题，能够有效利用排土场下游冲刷的软基区域的空间，可大幅度提高排土场的排土容积，能够显著提高整体排土场的稳定性，并为排土场的扩容提供了必要的前提条件。
