【摘要】 对西安地裂缝的运动发展规律进行了较深入的研究,预测了其未来发展变化的趋势和垂直位移沉降量。基于已有的研究资料,首先,总结和分析了西安f7地裂缝的运动发展变化,发现西安地裂缝的累积垂直位移沉降曲线呈现一定的规律性;然后,采用费尔哈斯特(Verhulst)模型,借用MATLAB的CFTOOL工具箱对其进行了回归拟合研究;最后预测了f7地裂缝未来发展变化的趋势以及年平均垂直位移沉降量。这样将会极大的方便对其进行预防以及采取相应的工程措施。更多还原

【Abstract】 The development regular of moving of Xi’an ground fissure is profoundly researched.At the same time,its future development tendency and vertical displacement of the moving are also predicted in the paper.Based on predecessors’ research data,firstly,the development regular of the moving of Xi’an f7 ground fissure is summarized and analyzed,simultaneously,it is discovered that the curve of cumulative vertical displacement of Xi’an ground fissure has some regularity.Then,based on Verhulst model,the regression analysis is adopted to fit the curve,by using MATLAB’s Curve Fitting Tool.Finally,the development tendency and the average vertical displacement for each year of the moving of f7 ground fissure are deduced.All these above-mentioned will greatly facilitate the ground fissure’s prevention and take some corresponding measures.更多还原
