The settlement is analyzed by using the settlement calculation theory already existed and the pile deformation modulus is researched under the different test conditions . it results in the different pile modulus of deformation that the pile side constraint is different because of the different testing conditions , so the settlement calculation for composite foundation of stone columns must use different computing modes based on the testing conditions 利用已有的沉降计算理论对沉降进行了分析，并对不同试验条件下的桩体变形模量进行了研究；桩体侧限阻力因试验条件不同而有差异，导致桩体变形模量的不同，故碎石桩复合地基的沉降计算应根据测试条件的不同选取相应的计算模式。
Integration of these two sides could let the results of layerwise summation method ( lsm ) be more accuracy , which can consider not only soil stress history but also soil lateral deformation and soil nonlinear properties even . ( 5 ) research on the application of meshless method for embankment settlement calculation 综合这两个方面，单向分层综合法的计算结果趋于更准确，其不但能考虑应力历史外，而且能计入土体侧向变形甚至土体非线性特性； ( 5 )路堤沉降计算无单元法应用研究。
Diagnostic characters for the recognition of species include the presence or absence of pectoral fin , the position of dorsal fin origin , gill opening , anus , nostril opening and eye , the cirri present or not , the dentition type , the body coloration , and the head pores or lateral line etc 一般依据胸鳍的有无或发达程度，背鳍起点、鳃孔、肛门、鼻孔和眼等的相对位置，颌的发达程度和颌上是否具须，齿的形状和排列方式，身体的斑纹，以及头部和体侧的侧线孔数目等进行鉴别。
A theoretical analysis of local damage in a thin ductile tube hit by a flat - nosed missile laterally is developed to predict local failure due to plugging by the beam - on - foundation model . the effect of internal press was considered , and differential equations was obtained which can predict the ballistic speed of the missile which impact the tube filled with water . it can be solved by runge - kutta method 采用地基梁模型对平头弹体侧向冲击钢管的冲塞型破坏模式进行了理论分析，考虑了充压情形下内压的影响，导出了钢管在冲击过程中的运动方程，可以用龙格?库塔法进行数值求解来确定弹体冲击充液压力管道的弹道极限速度。
When there is original stage support only , the load ratio of surrounding rock gets more and more bigger with the increasing of crust stress , correspondingly , the load ratio of initial stage support gets smaller . when the initial stage support and the second support act each other , the load ratio of surrounding rock is more than fifty percent , and it has little change with the increasing of crust stress . the whole analysis of the surrounding rock and support shows that the bottom arch of liner and the feet of liner have serious stress concentration , so do the sidewalls and the foot of a wall of the surrounding rock 通过屈曲理论分析结果对比表明，弹性屈曲和突变失稳分析的结果比非线性屈曲分析的结果要大得多，非线性分析由于考虑了材料非线性和几何非线性，因而结果与实际接近实际；当只有初期支护时，随着地应力的增加，围岩的荷载分担率增大，相应地，初期支护的荷载分担率就减小了；当有初期支护和二次衬砌共同作用时，围岩的荷载分担率在50以上，这一分担率随地应力的增加其变化不大；支护和岩体的整体分析表明，衬砌底拱及拱脚处应力集中严重，隧道岩体侧墙及墙角围岩的应力集中也较大。
