Abstract

The invention discloses a high-speed rail roadbed deformation self-adaptive control system and method. The high-speed rail roadbed deformation self-adaptive control system comprises a plurality of base displacement sensors, a reamer, a liquid storage tank and a controller, wherein the base displacement sensors and the reamer are buried below a roadbed, the reamer is composed of a plurality of adjacent and mutually independent cavities, a liquid input pipe and a liquid output pipe are arranged at the two ends of each cavity respectively and connected with the liquid storage tank to form a loop, an input valve is arranged between each cavity and the corresponding liquid input pipe, an output valve is arranged between each cavity and the corresponding liquid output pipe, and the controller controls the input valves and the output valves according to the displacement value of the base displacement sensor. The deformation of the high-speed rail roadbed is monitored, the differential settlement of the high-speed rail roadbed is effectively adjusted, the differential settlement of the base is adjusted in a self-adaptive mode, and then the smoothness and stability of the high-speed rail roadbed are improved.

Description

technical field [0001] The invention relates to the technical field of railway engineering, in particular to an adaptive control system and method for high-speed railway foundation deformation Background technique [0002] Compared with ordinary railways, high-speed railways have higher requirements and standards for subgrade deformation control. When the high-speed railway foundation needs to pass through soft rock or weak foundation, due to the relatively weak foundation rock and soil, it is easy to produce large deformation or differential settlement during the operation of the high-speed railway. When the high-speed railway base is located in the seasonal frozen soil area or at least in the area with abundant rainfall, due to continuous frost heaving, thawing, or multiple dry-wet cycles, the high-speed railway base is prone to large deformation or large differential settlement, which is serious Affect the safety of high-speed rail traffic. In order to ensure the safety...
