由于地质条件的隐藏性和勘察技术的局限性使许多因素不可预知或知之甚少,在区域尺度上进行地面沉降的计算和预测往往存在一定的困难.将地面沉降数值模拟公式作为迭代方程,提出了从随机动力系统的角度对地面沉降时空特征进行定性分析的方法,并提出了基于地统计学的不均匀地面沉降指数公式.利用不均匀地面沉降指数从动力系统的角度定性分析了北京地区地面沉降过程中表现出的时空特征.
Due to the hidden nature of geological conditions and the limitations of prospecting technology, many factors are unpredictable or poorly understood, and there are often some difficulties in calculating and predicting land subsidence on a regional scale. Taking the formula of land subsidence as an iterative equation, A method of qualitative analysis of space-time characteristics of land subsidence from the perspective of stochastic dynamical system is proposed and an inhomogeneous land subsidence index formula based on geostatistics is proposed.Using the inhomogeneous land subsidence index, the ground surface of Beijing area is qualitatively analyzed from the perspective of dynamical system The spatial and temporal characteristics of sedimentation.
