Static and dynamic drainage consolidation construction process method for deep soft soil area
The invention discloses a static and dynamic drainage consolidation construction process method for a deep and thick soft soil area, the method is characterized by comprising the following steps: leveling a site, paying off and partitioning; solidifying the shallow layer of the soft soil foundation of the in-field road area in situ; laying a vertical drainage system and a sand cushion layer; backfilling a soil filling layer; preliminarily putting into use and applying load; and backfilling to the designed elevation and hardening the pavement. Under the action of upper static load and dynamic load of the underlying soft soil layer, pore water is continuously discharged along the plastic drainage plate, the pore water pressure is gradually dissipated, the pore volume is reduced, the effective stress is increased, the shear strength index of the soil is improved, the post-construction settlement is obviously reduced, the engineering cost is reduced, and the method is safe and reliable. Soft soil does not need to be excavated when the surface layer of the roadbed is solidified in situ, the soft soil layer of an engineering site is fully utilized, the waste amount of sludge is reduced, and the economic and environment-friendly requirements are met. The construction period is shortened, and the manufacturing cost is saved. The social benefit is high and the economic benefit is good.
本发明公开了一种用于深厚软土地区的静动力排水固结施工工艺方法，其特征在于，包括如下步骤：场地平整及放线分区；场内道路区软土地基浅层就地固化；铺设竖向排水体系及砂垫层；回填填土层；初步投入使用施加荷载；回填至设计标高并进行路面硬化。下卧软土层在上部静力荷载及动力荷载作用下，孔隙水不断沿塑料排水板排出，孔隙水压力逐渐消散，孔隙体积减小、有效应力增加，土的抗剪强度指标提高，工后沉降显著降低。工程成本降低，安全可靠。本发明对路基表层就地固化无需对软土进行挖除处理，充分利用工程现场的软弱土层，减少淤泥的弃方量，符合经济环保要求。本发明缩短工期了工期，节省了造价。社会效益高，经济效益好。
