Emulation Calculation on the Magnetic Property of Engineer Obstacles in shallow Water

以设置在浅海拍岸浪区中含有钢轨的筑城性工程障碍为研究对象,从钢轨的材料特性及磁特性的分析入手,应用定量地学的方法,建立起了这一特殊工程障碍的磁场正演计算模型。在仿真计算的基础上,提出了采用磁通门磁梯度探测方案对这一特殊工程障碍实施有效探测的具体方法及其关键技术参数。仿真计算的结果与实际测量的结果基本吻合,据此提出的设计方案在工程研制过程中得到了充分的试验验证。

Regarding the engineer constructed obstacles included the steel rail in shallow water as the research target, starting with the analysis on the material characteristic and the magnetic property of the steel rail, this article sets up a magnetic field calculation model of this type of specific engineer obstacles by use of quantitative geognosy. Based on the emulation calculation, the article puts forward the key design parameters and the detailed method in which the engineer obstacles were detected effectively by using the magnetic fluxgate gradient detection technology. The result of the emulation calculation dovetails with the value of the actual testing, and the design scenario, which is put forward in accordance with the result of the emulation calculation and the actual testing, is validated in the course of engineer development phase sufficiently.
