查询词典 geostatic pressure

The similar material simulation is a kind of scientific experiment,this is one of ways that people discusses and understands geostatic pressure rules.

相似材料模拟是科学实验的一种，这是人们探讨和认识地压规律的途径之一，按矿山实际原型，按一定比例缩小做成模型，然后在模型中开挖巷道模拟采场工作，观察模型的变形、位移、破坏和岩层移动等情况。

然而就在这时，姚明的右腿与梅森的左腿发生碰撞导致重心不稳，重重地压在了梅森的身上。

This article in view of this kind of situation, to Da\\\anshan coal mine rockburst mechanism geostatic pressure mechanism, influencing factor, coal bed impact tendentiousness has conducted the research, promulgated the impact geostatic pressure through the numerical simulation to have the rule, to further prevention lay the foundation.

本文针对这种情况，对大安山矿冲击地压机理、影响因素、煤层冲击倾向性等方面进行了研究，通过数值模拟揭示了冲击地压发生规律，为进一步防治工作奠定基础。

Based on the equal strain consolidation model of sand drain ,and neglecting the well resistance and the vertical drainage consolidation,a layered model for the nonlinear consolidation of sand drain ,which accounts for the geostatic pressure varying along depth and the relationship between the average viod ratio and the logarithm of average effective stress,is presented.

基于砂井等应变固结模型，考虑初始有效应力沿深度变化，忽略井阻和竖向排水固结的影响，应用平均孔隙比与平均有效应力的对数关系，建立砂井非线性径向排水固结的分层计算模型，并求得常荷载作用下的径向排水固结解析解。

The Da＇anshan coal mine already entered the deep mining stage, Geologic structure is complex by the fold geologic structure primarily in the Minefield, the mining coal working surface and the tunnel impact geostatic pressure occurs frequently, but so far has not conducted the system research.

大安山煤矿现已进入深部开采阶段，井田内以褶曲为主的地质构造复杂，采煤工作面和巷道冲击地压发生频繁，但到目前为止还没有进行过系统研究。

The results of numerical analysis show that the elastic modular and the poisson ratio have no effect on two-dimensional bearing capacity, but can affect the ultimate bearing capacity of three-dimensional foundations and control the convergence and precision of finite element calculation; the earth pressure coefficient controls the geostatic stress of foundation, sequentially affects the ultimate bearing capacity of foundations and the convergence of numerical calculation. When calculating the ultimate bearing capacity of undrained saturated foundation, the complete formulation exists shear locking, and reduce formulation exists hourglassing, so the hybrid formulation is suitable to imitate the geomaterial. When the soil obeys nonrelevent flow rule, the yielding function is different from potential function, and the elastic-plastic matrix of soil is asymmetric, so the unsymmetry numerical solver and appropriate finite element mesh is required.

研究结果表明，土体弹性模量和泊松比对二维基础极限承载力没有影响，但是影响着三维矩形基础的极限承载力，控制着ABAQUS数值算法的计算精度与收敛速度；地基土压力系数控制着地基土体中的地应力平衡，从而影响着二维条形基础和三维矩形基础的极限承载力和地基破坏包络面；对于不排水饱和软黏土地基，常规的完全积分单元会造成剪力自锁现象，而减缩积分单元则存在过于柔化的现象，故采用杂交单元来模拟较合适；当土体服从非关联流动法则时，屈服函数与塑性势函数之间存在差异，从而导致土体弹塑性矩阵呈现非对称性，在有限元计算中必须采用非对称数值解法，并且合理地划分单元才能对极限承载力进行准确求解。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。
