Aimed at all kinds of damage phenomena in the sleeve usage of oil-film bearing in the backup roll of Baoshan 1580 hot strip mill,during the process of elastic conjunction between sleeve and rollneck,deformation and load properties are quantitatively analyzed by boundary element method for 3D elastic and plastic contact problems.

针对宝钢1580热连轧机精轧机组支承辊油膜轴承锥套使用中存在的各类损伤问题，利用三维弹塑性接触问题边界元法定量分析了轧机油膜轴承锥套与轧辊辊颈过盈装配过程中的变形和载荷特性，得出了装拆过程中不同的胀型压力和轴向推力条件下锥套接触压力延母线方向的变化规律，同时锥套端部和密封槽附近接触压力峰值的存在是加速锥套损伤及降低其使用寿命的重要原因。

The following results are got:(1) the analytical equation between the overburden pressure, the pore fluid pressure and the matrix stress is established;(2) the nonlinear relation between the porosity of saturated soils and the pore fluid pressure are obtained, which relates to the initial state and the initial pore pressure of saturated soils;(3) Based on the new principle, the rock shear strength theory and hydraulic fracturing pressure formulation are reacquired, which are much more reasonable than the traditional ones.

第二章讲述的是该有效应力原理的一些工程应用研究，通过该研究，我们取得如下成果：（1）建立了上覆岩层压力、孔隙流体压力、基岩应力之间的解析关系式；（2）推导出了饱和土体孔隙度与孔隙水压之间的非线性关系式，该关系式与多孔介质的初始状态及初始孔隙水压有关；（3）建立了基于多孔介质的岩石剪切强度理论和岩石破裂压力计算公式。

By analysising the datum in different prestressing force of piston spring shows that raising the prestressing force of piston spring only have a small influence on stroke time to keep the other paramters in costant, but the back stroke time will be decreased and the frequency, the percussive energy and the hydraulic efficiency will be increased rapidly.

对不同锤簧予压力下液动冲击器性能变化的试验数据处理、分析得出：在保持液动冲击器的其它参数一定时，增加锤簧予压力对冲程时间影响不大，但可以大大缩短返程时间，大幅度提高冲击频率、冲击功和液动冲击器的水力利用效率，增加锤簧的予压力是提高液动冲击器性能的一种有效手段。
