Reinforcing and surcharge structure used for preventing deep soft foundation dump against floor heave and instability
The invention discloses a reinforcing and surcharge structure used for preventing a deep soft foundation dump against floor heave and instability. The reinforcing and surcharge structure used for preventing the deep soft foundation dump against floor heave and instability is composed of a vertical-horizontal consolidated drainage system and a hierarchical surcharge preloading and counter pressingsystem. The vertical-horizontal consolidated drainage system is jointly composed of gravel piles (3), geotextile (2) and a gravel cushion layer (1). The hierarchical surcharge preloading and counterpressing system is located on the upper part of the deep soft foundation gravel pile vertical-horizontal consolidated drainage system and adopts large stone blocks, gravel and or broken stone materials to conduct graded surcharge preloading. According to the reinforcing and surcharge structure used for preventing the deep soft foundation dump against floor heave and instability, an effective drainage channel can be provided for saturated silts and other fine particle materials scoured on the downstream side of the dump, the internal drainage time of the soft foundation is shortened, consolidation of the saturated soft foundation is accelerated, the rock-soil mechanics index and bearing capacity of the base soft foundation are improved, the stability of the bearing capacity of the soft foundation in the surcharge preloading process is effectively improved and controlled, the internal floor heave is prevented, and settlement due to uneven inner stress is prevented.
本发明公开了一种用于深厚软基排土场防止底鼓失稳的加固与堆载结构，是由竖向－水平固结排水系统、分层堆载预压和反压系统组合构成，所述的竖向－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。本发明对于排土场下游冲刷的饱和泥沙等细颗粒物料能够提供有效排水通道，减少了软基内部排水时间，加快了饱和软基的固结，提高了基底软基的岩土力学指标和承载力，有效提高和控制堆载预压过程中软基承载力的稳定性，防止内部底鼓、内部应力不均匀沉降。
