Method for treating interaction foundation of soft clay layer and liquefied soil layer through pneumatic vibration rod compaction method
The invention relates to a method for treating an interaction foundation of a soft clay layer and a liquefied soil layer through a pneumatic vibrating rod compaction method. The method comprises the following seven steps of determining the depths of the liquefied soil layer and the soft clay layer in a site according to survey data; leveling the field, positioning a vibration point, and arranging a plastic drainage plate; positioning a pile machine; performing resonance sinking; performing high-pressure air injection; performing vibration hole vibration reservation; and performing vibration rod lifting. According to the method, the vibration hammer-vibration rod-foundation soil system is in a resonance state by adjusting the frequency of vibration hammers, so that effective transmission of vibration energy to soil bodes around vibration rods is achieved, vibration compaction of the liquefiable soil layer is achieved, and the liquefying property of the liquefiable soil layer is eliminated; and meanwhile, when the vibration rods sink to the soft clay layer, high-pressure air injection can promote dissipation of ultra-static pore pressure in soil caused by vibration loads, the drainage consolidation process of the liquefied soil layer and the soft clay layer can be accelerated in cooperation with plastic drainage plates, and the method is an economical, environmentally friendly and efficient method for treating the interaction foundation of the soft clay layer and the liquefied soil layer.
本发明涉及一种气动振杆密实法处理软黏土层和液化土层交互地基的方法，包括根据勘察资料，确定场地液化土层和软黏土层所处深度；整平场地，定位振点，打设塑料排水板；桩机定位；共振下沉；高压喷气；振孔留振以及振动提杆七个步骤，本申请通过调节振动锤频率使得振动锤‑振杆‑地基土系统处于共振状态从而实现振动能量向振杆周围土体的有效传递，实现可液化土层的振动密实从而消除其液化性；同时，当振杆下沉至软黏土层时，高压喷气可促进振动荷载引起的土中超静孔压消散，配合塑料排水板可以加速液化土层和软黏土层的排水固结过程，是一种经济、环保、高效的软黏土层与液化土层交互地基处理方法。
