【摘要】 本文基于隔河岩工程原型位移监测资料,对大坝混凝土弹性模量进行反演,首先对原型位移监测资料采用逐步回归得出大坝位移统计模型,并分离出水压位移分量,再利用有限元结构分析软件ANSYS获得理论水压分量,通过反演从而求出大坝混凝土的平均弹性模量。结果表明,此法获得的弹性模量接近真实情况,为评价大坝安全性态提供了可靠的依据。更多还原

【Abstract】 The paper engages the inversion analysis of concrete elastic modulus of dam based on prototype displacement monitoring data, First, gets the statistic model of dam displacement with progressive regression and separates the displacement component of water pressure from it, again gets the theoretical component of water pressure with ANSYS, gets the mean elastic modulus of dam concrete by way of inversion analysis. The result indicates that the got elastic modulus is close to the real state and provides reliable basis for the evaluation of dam safe.更多还原
