本文分析的主要原理：首先根据经验，初估路面结构层应力应变非线性参数，利用计算机程序模拟承载板试验测回弹弯沉的过程，通过现场实测的弯沉数据来检核该模拟过程的真实性，设定目标函数，选定适当的优化反算方法，当目标函数不满足时，即利用该优化反算方法调整本构模型参数，使得模型能够逐步向真实解逼近，当目标函数得到满足时，则认为此时反算得到的路面结构层的应力、应变、位移场为真实的应力、应变、位移场，所推算得到的非线性应力应变模型为真实的路面结构层应力应变模型。

In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

Some conclusions are drawn as follows: The total tendency of socles is basin-shaped settlement which is bigger in the middle position socles than the peripheral position socles before the pile foundation underpinning. Pile foundation underpinning augments the differential settlements. After soil excavation, middle position socles rebound obviously owing to unloading action, which lessens the differential settlements between middle and peripheral position socles.
