Embodiment Construction

[0046] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0047] Such as figure 1 , figure 2 , image 3 , Figure 4 A one-dimensional horizontal cyclic load loading device shown includes a model tank 1, a loading system, and a monitoring system. Through the loading system, cyclic loads such as simulated storm load and wave load are applied to the model pile 10 as the experimental object, the readings of the strain gauge 9 are recorded, and the displacement path diagram of the pile top is drawn, so as to study the working condition of the single pile under the action of one-dimensional horizontal cyclic load , In addition, this device can also apply horizontal static load and vertical static load to the model pile 10 so as to conduct research on the ultimate bearing capacity of a single pile. The device can be widely used in the research of pile foundation engineering, and is easy to use, and the e...

Abstract

The invention relates to the field of pile foundation project study, and aims at providing a one-dimensional horizontal circulation load loading device and an experiment method thereof. The one-dimensional horizontal circulation load loading device comprises a model groove, a loading system and a monitoring system. The interior of the model groove is used for being filled with filling soil and provided with a model pile. The loading system comprises a hydraulic servo actuator, a computer control system, a counter-force frame, a hydraulic jack, a positioning support and a positioning support guide rail. The monitoring system comprises a strain gage and a data collecting system. According to the circulation load loading experiment method, the horizontal circulation load is exerted on the model pile, real-time monitoring is carried out, and the working characteristic of the model pile under the action of the horizontal circulation load, the bearing force weakening situation and the influence range on the surrounding soil are studied. A series of one-dimensional horizontal circulation loads such as the wave load, the windstorm load and the earthquake load are simulated by changing the conditions such as the load amplitude, the load average value, the number of circulation times and the circulation frequency.

Description

technical field [0001] The invention relates to the field of pile foundation engineering research, in particular to a one-dimensional horizontal cyclic load loading device and an experimental method thereof. Background technique [0002] In recent years, as the development of the ocean has been paid more and more attention, more and more projects are built in the ocean. The influence of horizontal cyclic loads such as wind load, wave load, and earthquake load on buildings and their pile foundations has gradually been paid attention to. The horizontal cyclic load of the building in the ocean is very different from the horizontal static load. Since the cyclic load is a process of repeated loading, various factors will have a great impact on the bearing capacity of the pile. The working state of the pile under load is very complicated. [0003] Under the action of cyclic loading, the working properties of piles are also very different under different conditions. The loading fr...
