Modeling and Simulation for Earth-pressure-balance Simulated Test System of Double-O-tube Shield Based on Constant-pressure-network

采用功率键合图法建立基于恒压网络的单圆盾构土压平衡模拟实验系统仿真模型,并验证模型的有效性。在此仿真模型基础上,利用仿真模型不受物理条件限制的优点,建立了基于恒压网络的双圆盾构土压平衡模拟实验系统仿真模型,并进行了仿真研究。仿真结果表明,模型可基本实现双圆盾构土压平衡模拟实验系统的工况模拟,对建立基于恒压网络的双圆盾构土压平衡模拟实验系统有借鉴作用。

The simulation model of earth-pressure-balance system of single-O-tube shield based on constant-pressure-network was established and verified. On the basis of the model, the simulation model of earth-pressure-balance system of double-O-tube shield based on constant-pressure-network was established, by taking advantage of the previous simulation model which is not restricted by the physical condition. The simulation results show that the later model can basically realize the simulation of the situation of the simulated test system of double-O-tube shield.
