The author suppose, the anisotropically undrained shear strength is applied for the first time in the analysis of resistant heave stability for deep braced excavations in the world, the safety factors of two kinds of stability failure are gained, the first kind of factor is stability against sliding, the second is losing the ultimate bearing capacity.

在国内外首次将各向异性不排水剪强度应用到深基坑抗隆起稳定分析中，推导抗滑稳定破坏（包括浅桩支护及刚性支护）和丧失极限承载力破坏两种情况下的稳定安全系数公式，对典型上海软土的模型参数进行计算分析，并对各参数对安全系数的影响进行讨论，最后以三个工程实例加以验证。

A number of significant conclusions are proposed. For the first time,double arciform strain of the soil nailing is observed in the miscellaneous fill. It is considered as the result that there are two potential slide planes in the miscellaneous fill. The critical anchorage length is analyzed and determined for the first,which is 9 m in this experiment. T...

首次测得并分析了杂填土中土钉的双弓形应变分布形态，指出这是填土边坡中存在2个或以上潜在滑动面的结果；首次测得并分析了土钉临界锚固长度，指出在本试验条件下，其长度约为9 m，并认为临界锚固长度是应变峰值点、零值点和破坏点同时发生转移而形成，锚固类结构均具有此特点。

This thesis mainly employs the density-matrix renormalization group to investigate the valence bond model. We deal with the one-dimensional and quasi-one dimensional benzenoid systems from medium to infinite sizes successfully and get the ground state energies, the first excited state energies and other properties for the first time.

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.
