Structural soft soil vacuum preloading field model test device and method
The invention discloses a structural soft soil vacuum preloading field model test device and method.The test device comprises a sampling cutting ring cylinder, a cutting lifting plate, an upper sealing cover, a permeable stone, a drainage plate, a connecting hose, an air pump, a monitoring device, a flexible sealing film, a heap load and the like. A soil body is lifted out through a cutting lifting plate and placed on a field permeable stone, meanwhile, a drainage plate and a monitoring device are arranged through a cutting tool, disturbance of a test to structural soft soil is reduced to the maximum extent, and therefore an optimal vacuum preloading reinforcement scheme closer to the actual engineering field is obtained. The test device is flexible in structure, can be applied to large-volume soft soil field model tests in different modes such as vacuum preloading, surcharge preloading and vacuum-surcharge combined preloading, and can meet the requirements of different drainage channel designs, different vacuum environment designs and different monitoring scheme designs, so that the purposes of improving the engineering quality and reducing the construction cost are achieved. And the expenditure is saved.
本发明公开了一种结构性软土真空预压现场模型试验装置及方法，试验装置包括取样环刀筒、切削起吊板、上密封盖、透水石、排水板、连接软管、抽气泵、监测装置、柔性密封膜、堆载重物等，采用薄壁带刃环刀筒缓慢压入结构性软土，利用切削起吊板提出土体，放置于现场透水石上，同时利用切削工具安置排水板和监测装置，最大限度降低试验对结构性软土的扰动，从而得到更接近于工程现场实际的最优真空预压加固方案。本发明的试验装置结构灵活，可应用于真空预压、堆载预压、真空‑堆载联合预压等不同方式的大体积软土现场模型试验，能够满足不同排水通道设计、不同真空环境设计、不同监测方案设计的要求，从而达到提高工程质量，节约经费的有益效果。
