Indoor test method for scouring protection of pile foundation solidified soil
The invention discloses a pile foundation solidified soil scouring protection indoor test method which comprises the following steps: erecting a transparent model pile in a grit chamber of a water tank, and paving a soil layer on the periphery of the model pile; an ADV flow velocity sensor is arranged in front of the model pile, a video recorder is arranged in the model pile, and flow velocity data and image data in the test process are recorded; solidified soil is manufactured; slowly injecting water into the water tank until a corresponding water level is reached, adjusting water tank flow making equipment to enable water flow to reach a designed flow speed, and flushing at the corresponding flow speed until the flushing pit develops in a balanced manner; according to the range and depth of the scour pit, the scour pit is filled with solidified soil in a blowing mode; and observing and measuring the scour development condition in the solidified soil solidification process until the scour pit develops in a balanced manner, and recording the scour depth and scour range of each measuring point around the model pile. According to the invention, the defect that the requirements of research work on environmental conditions, test working conditions, test precision and the like are difficult to completely meet by field test is overcome.
本发明公开了一种桩基固化土冲刷防护室内试验方法，包括：在水槽的沉砂池当中竖立透明的模型桩，在模型桩周边铺设土层；在模型桩前布置ADV流速传感器，模型桩内布置录像机，记录试验过程中流速数据和影像数据；制造固化土；向水槽中缓慢注水直至达到相应水位，调整水槽造流设备使水流达到设计流速，在对应流速下冲刷至冲刷坑发展平衡；根据冲刷坑的范围及深度，将固化土吹填至冲刷坑中；观察并测量在固化土固化过程中冲刷的开展情况，直至冲刷坑发展平衡，记录模型桩周围各测点的冲刷深度与冲刷范围。本发明克服现场开展试验测试难以完全满足研究工作对于环境条件、试验工况、测试精度等要求的缺陷。
