Thissubject exerts the experiment method of analogue modeling, and we take geologic mining condition of the Xin Zhi Colliery of Huo Zhou Mineral Bureau in Shang Xi province as the physical model of background design. The experiment is divided into two phases, the first phase simulates the course of mining subsidence, we study rule of movement transmogrification of mining terrane. In the second phase, after the mining subsidence is gradually stabilization, we bring into bear different load in the different location of subsiding basin, and we study ground stability with goaf.

本课题以山西霍州矿物局辛置煤矿地质采矿条件为例，进行了相似材料模拟试验，试验分为两个阶段：第一阶段模拟开采沉陷过程，研究采动岩层移动变形规律；第二阶段在开采沉陷基本稳定之后，在沉陷盆地的不同位置施加大小不同的建筑物荷载，研究其地基的稳定性。

When a plate anchor is buried in the clay and subjected to uplift force, the difference of excess pore pressures on anchor top and base results in suction force, which may be beneficial to improve the uplift resistance of anchor, especially when wind and wave loadings apply quickly.

当黏土地基中的平板锚承受上拔力时，平板上、下表面超静孔压差形成的吸力使其抗拉承载力显著增加，对于风浪等快速加载条件尤其如此。

The research contents mainly include: First, the influence of foundation constraint condition to the temperature stress is analyzed, the temperature stress formula of ultra-long concrete anchor plate is deduced, then the influence of length to structure crack can be gotten from the formula. Second, a breathing method is set up to solve the problem of temperature stress in ultra-long concrete constructions. By setting the sliding floor, a breathing system is built up and the temperature stress reduced distinctly. Third, the effect of prestress technique in the control of temperature stress is analyzed, it is simulated and calculated through FEA to get the right way to apply the prestress. Forth, the delay of temperature field and unsteady conduction is considered, the temperature field of ultra-long concrete structure with later poured band is simulated, then temperature stress distribution after casting the concrete is calculated, finally the effect of later poured band to temperature stress of ultra-long structure is analyzed.

本文的研究内容主要包括：(1)分析了基础约束对超长混凝土结构温度应力的影响，推导了超长混凝土地基板温度应力公式，从而得出长度对结构裂缝的影响；(2)针对超长混凝土裂缝问题，提出了一种可呼吸的解决方法，通过设置滑动层，使结构成为一种"可呼吸"体系，从而有效的降低温度应力；(3)分析了预应力技术在控制超长结构温度应力中的作用，通过有限元模拟计算，得到合理的预应力施加方式；(4)考虑温度场的滞后效应及不稳定传导，对带后浇带超长混凝土结构浇注后的温度场仿真模拟，计算浇注后的温度应力分布，分析后浇带对超长结构温度应力的影响。
