西安市铁炉庙地裂差异沉降的二维有限元模拟

西安地裂差异沉降近期超常活动，给城市建设造成了严重的经济损失和危害，并对将要建设的地铁工程危害极大，根据近几十年来的实测和预测资料，通过建立二维有限元模型和地裂差异沉降的二维有限元仿真模拟，得出2005年到2050年地裂差异沉降累积值为84．7mm，水平位移量为36．3mm．这与用各种数学模型计算的结果基本吻合．

Forecasting the Rate of Taphrogenic Differential Settlement of Tielu Temple with Two-dimension Limited System Theory in Xi'an City

The extraordinary activity of taphrogenic differential settlement of late caused great damage and economy loss to urban building, it will greatly jeopard the tunnel engineering recently . Two-dimension limited system theory and simulation modeling to two-dimension limited system theory for Xi'an taphrogenic differential settlement was set up based on real and forecasting data near umpty years. It concludes that the accumulation value of taphrogenic differential settlement is 84.7 mm and the horizontal shift value is 36.3 mm from 2005 to 2050. The result is foundational fit to computational consequence using varieties of mathematical model. The affect of taphrogenic differential settlement 45 years later is analyzed, which come from forecast, on subway tunnel, and the taphrogenic differential settlement will break subway tunnel 45 years later. Therefore, an effective measure to limit exploitation of deep pressing groundwater and strengthen the construction technology and materials of subway tunnel was adopted,respectively.
