Problems solved by technology

In order to make up for the limitations of theoretical analysis, for important projects, it is necessary to conduct analysis in combination with indoor model tests. The key technology is how to simulate the long-term vertical and horizontal cyclic loads on the foundation, but no reports on this issue have been found so far.

Abstract

The invention relates to a test system for simulation of long-term cyclic loading effect. The test system comprises a long-term cyclic loading device, a mold tank, a vertical cyclic loading matching device and a horizontal cyclic loading matching device. The mold tank is filled with soil for the test and a mold base is embedded in the soil body for the test. Through the long-term cyclic loading device and the vertical cyclic loading matching device, a vertical cyclic loading simulation test is realized. Through the long-term cyclic loading device and the horizontal cyclic loading matching device, a horizontal cyclic loading simulation test is realized. Compared with the existing test system, the test system has a wide application range and high simulation precision, beaks through the limitation of only vertical and horizontal single-direction loading function of the existing test system, realizes simulation of vertical and horizontal cyclic loading conditions, and has accuracy self-balance function and long-term cyclic loading function.

Description

technical field [0001] The invention relates to a model test loading device, in particular to a test system for simulating long-term cyclic load action. Background technique [0002] With the rapid development of the economy, more and more sea-crossing bridges and new energy projects have been built one after another. Sea-crossing bridge projects, such as Qingdao Bay Bridge, Hangzhou Bay Bridge, Zhoushan Sea-Crossing Bridge, Xiamen-Zhangzhou Sea-Crossing Bridge, The Nan'ao Sea-Crossing Bridge and the Hong Kong-Zhuhai-Macao Bridge have greatly shortened the distance between regions, accelerated the flow of production factors and economic integration between regions, and boosted the economic development of coastal areas. New energy projects, such as wind power generation, as a zero-pollution energy source, have become the main development direction to achieve clean power and meet power consumption in recent decades. my country's northwest region, northern plain region and sou...
