Guide-enhanced barrel-shaped foundation penetration test model device and method
The invention discloses a guiding-enhanced barrel-shaped foundation penetration test model device and method. The device comprises a test system, a water supply system and a negative pressure adjusting system. The test system comprises a mounting top cover, a foundation guide device, a model box and a barrel-shaped foundation. Due to the design of the mounting top cover, the number of cylinder walls is reduced, and energy consumption is reduced; the foundation guide device ensures that an offshore type barrel-shaped foundation model is maintained vertical in the penetration process, and test errors are avoided; saturated soil is prepared in the model box by adopting an underwater throwing and filling method, the operation is simple, and the marine soil layer precipitation process is effectively simulated; inverted filter geotextile is arranged at a water inlet valve port, so that the water inlet pressure can be reduced, and water surface fluctuation is reduced; a perforated bottom plate of a L-shaped wave absorbing plate can weaken the scouring effect of water flow on a soil layer in the test water adding process, and a perforated side wall can eliminate water waves generated in the water adding process of a water inlet valve; and the device and method can be used for simulating mounting and penetration process of the offshore type barrel-shaped foundation in a marine environment, and perfecting an excavation-free design calculation method and related construction technologies.
本发明公开了一种导向增强的桶型基础沉贯试验模型装置及方法，该装置包括试验系统、给水系统和负压调节系统；试验系统包括安装顶盖、基础导向装置、模型箱和桶型基础；安装顶盖的设计减少了筒壁数，从而降低能耗；基础导向装置保证离岸式桶型基础模型在贯入过程保持垂直，避免试验误差；在模型箱内采用水下抛填法制备饱和土，操作简单，有效模拟海洋土层沉淀过程；进水阀口处设置反滤土工布，可降低进水压强，减少水面波动；L形消波板的带孔底板可削弱试验添水过程水流对土层冲刷作用，带孔侧壁可消除进水阀加水过程产生的水波；本发明可用于模拟海洋环境下离岸式桶型基础安装、沉贯过程，完善免开挖设计计算方法和相关施工技术。
