沉降反演分析在储油罐基础纠偏中的应用
摘要:依托某一储油罐具体工程实例,利用传统的分层总和法和最小二乘法原理,建立了一个沉降反演分析数学模型。根据充水试验获得的地层沉降变形参数和所建立的数学模型对地层的相关参数进行了反演分析,得出了地层的当量模量、压缩模量以及基础的最终沉降量和倾斜量,为储油罐基础纠偏方案的制定提供了参考依据。提出的方法原理清晰,模型简单,计算方便,对其他相似工程有参考价值和指导作用。
Abstract:Based on a concrete engineering example of oil tanks,a mathematical model for settlement back-analysis is established in this paper by using the traditional layer-wise summation method and the principle of least square method.In the meanwhile,according to the strata subsidence deformation parameters obtained by the water filling test,a settlement back analysis related to the stratum parameters is carried out with the established mathematical model.Thus the equivalent modulus and compression modulus of stratum are calculated;the final subsidence and tilt rate of oil tank foundation are worked out as well.And the results can provide some references for the rectifying plans of oil tank foundation.For the proposed method in this paper,its principle is clear,the model is simple and the calculation is convenient,and it also has reference value and guidance for other similar projects.
