Microscopic simulation device for deep side wall friction resistance of foundation pile
The invention relates to a microscopic simulation device for deep side wall friction resistance of a foundation pile. Liquid is introduced into a pressurizing bag through a pressurizing opening, and the pressurizing bag pressurizes a soil body model, so that the stress level of a deep soil body is effectively simulated; and the stress of the soil body model and the stress of a foundation pile model can be monitored in real time, and the foundation pile model is convenient to replace. The microscopic simulation device can be used for model tests of ultra-long foundation piles, under the condition that the size of the model is reduced, the micro deformation of the model can be effectively captured, and the stress loss of the soil body of the model is avoided; and the stress state of the soil body around the real deep pile can be simulated in a small-size model box. The microscopic simulation device can be combined with a geotechnical engineering PIV technology, and can effectively capture and analyze the micro deformation.
本发明涉及一种基桩深层侧壁摩阻力微观模拟装置，通过加压口向加压袋通入液体，加压袋对土体模型进行加压，以此对深层土体应力水平的有效模拟；且土体模型、基桩模型应力可实时监测，基桩模型更换便捷。本发明可用于超长基桩的模型试验，在缩小模型尺寸的情况下，能够有效捕捉模型的微小变形，并避免模型土体应力损失；并且能够在小尺寸的模型箱内模拟真实深层桩周土体的应力状态。本发明还可以与岩土工程PIV技术结合，能够有效捕捉与分析微小变形。
