摘　　要：温度形变场是个时间、空间等多因素耦合的复杂物理场,其对大体积混凝土结构产生形变的影响不容忽视.本文基于IBIS-L地形微变远程监测系统,研究某场地桩板墙大体积混凝土结构随温度变化的实时形变量;采用ANSYS数值模拟软件建立数值分析计算模型,计算因温度变化而引起的桩板墙形变量;对比实时监测微变与温度形变场数值模拟的结果,研究大体积混凝土桩板墙发生微变与温度形变场之间的相关性,为以后桩板墙的设计和防护提供理论依据.The temperature deformation field is a time-space and multi-factors coupling physical field,the effect of deformation on massive concrete structure can not be ignored. Based on the micro-deformation monitoring IBIS-L system,the real-time temperature-dependent deformation of the massive concrete structures of a sheet pile wall is monitored. According to the mathematical simulation software ANSYS,the correct numerical calculation is established. Furthermore,the sheet pile wall deformation caused by temperature variation is calculated. Through comparing the constant deformation of field monitoring with the results of temperature deformation field numerical simulation,the dependency of mass concrete pile between micro-deformation and temperature deformation field is researched.This can provide a certain theoretical basis for the design and protection of the pile wall.
