摘　　要：采用室内试验方法,研究了橡胶垫材料的变形过程,得到了变形量随着加载和卸载过程的变化曲线,进一步得到试验数值的拟合曲线。研究结果表明,橡胶垫的压缩性能良好,常用的单片橡胶垫不可恢复变形量在0.50~0.55 mm,这一结论对盾构法施工的研究有一定的指导意义。The mechanical properties of the rubber pad material deformation curve with the loading and unloading process were numerical experiments were obtained. The results shows that the were researched by laboratory test. The obtained, then the fitting curves of the compression performance of the rubber pad well, the unrecoverable deformation of the used monolithic rubber pad is between 0.50~0.55 mm. This conclusion has certain guiding significance to the study of shield construction.
