The main jobs of this paper are as followed: 1 The reuse of the frame design technology for aircraft assembly fixtures is researched. a frame line part library is built with the templet driven technology, the reuse of the frame line part come true by the tools for instantiation and instance modification. The design resources are effectively used, some repeating work is cut. 2 Two methods to obtain the assembly feature are proposed: the straight way by the Enumeration method and the indirect way by project features to the assembly plane. All of the assembly features of the frame and the adjustable bearings are obtained by these two methods which makes the frame automatic assembly technology for aircraft assembly fixtures come true. 3 The frame automatic assembly technology aircraft assembly fixtures based on assembly features is researched. A binary tree assembly model is used to express the assembly information of the frame for aircraft assembly fixtures, the automatic assembly between the frame, the aircraft and the adjustable bearing is completed within the three steps: distribute, obtain and evaluate assembly feature. Finally, the efficiency of the frame assembly design is proved. 4The frame interpart modeling technology for aircraft assembly fixtures is researched, the intersection methods are concluded and the arithmetic of the single-cut, double-cut and inter-cut intersection is proposed, the interpart fast modeling of the frame design for aircraft assembly fixture come true. 5Based on the researches mentioned before, a sub-system of frame fast design for aircraft assembly fixture is developed on CATIA. The sub-system is used to design the aircraft assembly fixtures in a large aeronautics corporation and make a good- effect.

Results of eight investigations make use of the soil experience and analysis form the disaster area of 921 earthquakes, The result of soil investigation and analysis form the disaster area of 921 earthquakes, Understanding such as: 1. The recommand degree depth of drive stake is 40% of stake length for stake and wattling method on dry soil condition. And 58% of stake lengths on unsaturated condition. And 67% of stake length on soil saturated condition.

This analytical approach shows that, as increasing the wear flat of indenter, the maximum indentation force needed to develop critical plastic zone increases and its corresponding critical penetration depth also increases slightly, Note that the effect of wear flat will affect rock fracture behavior. In addition, regarding the simulation of the effect of doubled-indenters, result shows that two adjacent indenters may interact each other as reaching the transient/critical relative space between indenters of 2~3. It dicpicts that a proper spacing arrangement between indenters may enhance a efficient mechanical cutting due to the less required maximum indentation force and energy dissipation.

由数值模拟之结果得知，当楔尖磨耗增加时，岩材产生脆性破坏之初裂贯切力随之增加，而其对应之临界贯入深度则亦微幅增加，故磨耗效应确会干扰岩材脆性破坏机制之形成；而由双刀效应之模拟，可知两贯切刀楔互制影响之破坏裂缝生、衍行为，当双刀相对刀距为时，岩材之破坏特徵有明显变化，即定义此为临界相对刀距，并探讨其产生脆性破坏所需初裂贯切力之变动范围及应力重叠区，由此得知适当之刀距安排将有助於减少能量之耗损。
