多级加筋土挡墙内力分布及变形规律研究

目前加筋土挡墙在国内迅速发展,各地修建的挡墙高度也在不断提高.但每年仍有许多挡墙由于设计缺陷发生事故.因此,对于多级加筋土挡墙内部受力及变形规律的研究显得十分重要.通过现场监测和有限元模拟相结合的方式,研究了加筋挡墙中墙背土压力、墙面位移、筋带应变的分布规律,为工程设计提供了优化建议.

Study on Internal Force Distribution and Deformation Rules of Multi-step Reinforced Soil Retaining Wall

Reinforced soil retaining wall develops rapidly in the country at present and the height of the wall built everywhere also increases continuously; however, there are still accidents arising out of design defects on the wall. Therefore, it is important to study the internal force distribution and deformation rules of multi-step reinforced soil retaining wall. This paper, by field monitoring and FEM simulation, studied the laws of the wall back soil pressure, wall surface displacement, and strain distribution in the reinforcement, which offers optimized proposal for engineering design.
