平衡压力

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。

Examination of the equilibrium status of a point in the salt water zone and the description of piezometric heads at two points in both the salt water and fresh water zones reveals that the location of the fresh water-salt water interface in a coastal homogeneous, isotropic unconfined aquifer can be estimated based on piezometric heads at two points in the same vertical line tapping respectively the salt water zone and the fresh water zone (from the water table to the interface) when the groundwater flow system is in a steady state and satisfies the Dupuit assumption.

If inflationary pressures will appear in China, it will have chance to revaluate its currency, and by doing so, slowly, on the long run the unbalances of world economy will be reduced.

如果通胀的压力出现在中国，这将有机会使人民币升值，这样，慢慢地，就从长期来看，世界经济的不平衡将得到改善。

The results show that the effects of pressure on tautomeric equilibrium constant K〓 is very limited at pressures much higher than the phase separation pressures, while the K〓 increases sharply as the pressure approaches the critical pressure or the bubble point pressure of the mixed solvents.

结果发现，在分相点附近化学平衡常数随压力变化十分敏感，这一特殊现象与混合流体中特殊的分子间相互作用与聚集密切相关。
