要改变我国重型机械设备的落后面貌,需要克服三种传统倾向性观点的阻力,采用符合时代特点的造型风格。作者从重型机械的特征出发,提出对这类机械造型风格的看法,包括:重而不笨、大而不繁、单纯大方、讲求线型,采用稳重明快色彩及通过遮护显优藏缺等十点,供重机设计者研讨。

Abstract This paper presents a new method for calculating the dynamic response of a rectangular plate, by combining me finite strip method and transfer substructure method. This algorithm can not Only save storage space, but also utilize the duplication of the strip. Thus it improves the computational efficiency and gives results of high accuracy as by the finite strip method. It is suitable for application in engineering practice.

On the design of Dahuofang hydraulic project during 1952, the problem of anti liquefaction for the sandy shell was extensively researched and learned from foreign reference books. With respect to our laboratory result of critical porosity ratio, we adopted the relative density 0 83 for the sand mass,its corresponding dry density and shear strength were cited in the analysis of slope stability by pseudostatic method, and two directions of earthquake inertia force were applied to this analysis. ln order to compact the sand to meet the relative density mentioned above, we developed the heavy machine tamper. During 1992, 5 exploring pits were dug in the sand shell to determine the undisturbed porosities,dry densities,relative densities and the mean value of relative density for 5 samples is 0 81 with 2 samples valued 1 0. The maximum shear modulus,maximum damping ratio,the relationship between shear modulus vers shear strain, damping ratio vers shear strain ,dynamic pore water pressure vers dynamic shear stress were determined by resonance column and dynamic triaxile tests. The static and dynamic stresses and strains of the dam were computed by FEM. The contours of liquefaction degree and the seismic safety factor graph were shown in the paper. The conclusion is: when earthquake with intensity Ⅷ occurs, the maximum liquefaction degree is 0 6,the minimum safety factor is 1 08.

1952 年设计大伙房水库工程时,对砂质坝壳抗震问题进行了广泛探索。遍阅苏、美、英书刊,进行砂料临界孔隙比试验。确定采用相对密度0-83 ,以防止砂料液化,用与此相应的干密度和抗剪强度及水平、铅直两向Ⅷ度地震加速度系数进行拟静力法坝坡抗震稳定计算。施工时,为了达到相对密度的要求,研制了重型机械夯板。1992 年,在坝体挖5 个试坑测原状孔隙率、干密度,在试验室测得平均相对密度0-81 ,其中2 个试样相对密度达1-0 ,用共振柱法和动三轴试验测得最大剪切模量、最大阻尼比、剪切模量- 剪应变关系、阻尼比- 剪应变关系、动孔隙水压力比- 动剪应力比关系。进行静力、动力有限元分析结合上述试验曲线得到坝壳坝基液化度等值线和坝坡抗震稳定安全系数时程曲线。Ⅷ度地震时,液化度最高处为0-6 ,安全系数最小为1-08 ,满足抗震要求。
