Abstract

The invention discloses a field simulator for simulating accumulative settlement of a foundation under the action of traffic load and a method for simulating the same. The invention solves the problems that the prior art lacks effective and normative simulation devices so that the accumulative settlement discipline cannot be studied scientifically, and achieves the automatic simulation of the traffic load with adjustable parameters and convenient operation. The structure of the field simulator comprises a bracket, wherein a loading plate and a displacement detecting device are arranged in the bracket; a guiding device is arranged on the upper part of the bracket and is connected with a cylinder which is connected with the displacement sensor; the displacement sensor is connected with a control device; the control device is further connected with an air circuit switching device; and one end of the air circuit switch device is connected with the cylinder, while the other end is connected with an air pump.

Description

Technical field: [0001] The invention relates to an on-site simulation device and simulation method of foundation cumulative settlement under the action of traffic load, belonging to the field of traffic and transportation engineering. Background technique: [0002] At present, for low subgrades, repeated vehicle action will cause cumulative settlement of the foundation. However, in the field, this cumulative settlement occurs simultaneously with the consolidation settlement caused by the self-weight of the subgrade, making it difficult to separate the cumulative settlement caused by vehicles from the total settlement, which makes it difficult to study the law of cumulative settlement. Therefore, there is an urgent need for a method to directly simulate the cumulative settlement caused by vehicles on the foundation. Invention content: [0003] The purpose of the present invention is to solve the problem that there is no effective standard simulation device at present, and...
