Based on a thorough analysis of the character and mechanism of city-retaining-wall structures, the design theories, construction technology, new wall types and development tendency are deeply discussed. Besides, the characteristics of various types of city retaining wall are discussed, and the usual methods for earth pressure calculation are summarized. For the anchored bar retaining wall, the anti-pulling bearing mechanism of anchored bar is first probed into, from which anti-pullforce computation method are obtained. Combined with quite a few engineering examples and spot tests, the advised design and calculation methods of anchored bar are verified. From the abundant spot measured date, an adjusted hyperbolic model is put forward to determine the anti-pullforce bearing capacity. Furthermore, a new type of H-like block retaining structure is advised with its working mechanism deeply discussed as well.

By starting with the basic theory of metropolis ring spatial development and drawing the experience of domestic and foreign metropolis ring, the paper makes a discussion on efficiency of metropolis ring pattern, development phases and spatial structure. It points out the three main phases of metropolis ring development—rudiment, growth and autumn. From the spatial structure, the paper stresses that metropolis ring has the features of "ring and layer", the size of the "ring and layer" has the direct ratio with city size, convenient degree of external transportation and city radiant intensity. It owns the idea that adjustment and control of metropolis ring spatial development should reflect the following concepts, including globalization, regional integrated harmony, views of scientific development, harmonious society, consultative city planning, people-oriented principle, guided city planning and responded city planning.
从都市圈空间发展的基础理论入手,借鉴国内外都市圈发展的经验,本文对都市圈模式效应、发展阶段和空间结构进行了探讨,认为都市圈发展阶段主要分雏形期、成长期和成熟期三个阶段;从空间结构看,都市圈具有"圈层式"的特征,圈层的大小与城市规模、城市对外交通的便利程度、城市对外辐射强度成正比;都市圈空间发展调控应体现全球一体化理念、区域整体协调理念、科学发展观理念、构建和谐社会理念、协商规划理念、以人为本理念、导向型规划理念和规划应变性理念。

Utilized the correlative knowledge of mathematics and theoretical mechanics, the movement measure of the rolling forming of rectangle ring have been studied that based on the ring rolling theory. And the corresponding geometrical models and mathematical models have been established. It was revealed the variation law of ring in the cold rolling process.With the rolling processing, the inside and outside diameters of ring gradually increased with the cures similarly hyperbolic and the augment speed of the inside diameter was obviously larger than the augment speed of the outside diameter. With the rolling processing, the displacement, speed and acceleration of the ring centre gradually increased in the feeding direction in the horizontal and vertical ring rolling mill. With the rolling processing, the moment of inertia which ring reeled its centre and the whirligig of ring gradually increased. It caused the rotary speed gradually decreased. And it was benefit to decrease the circle tolerance and improve the precision of final molding.

This contributes to the rigidity of the bearing and a precise radial guidance of the shaft. For special applications, full-complement cylindrical roller bearings are employed. The cylindrical roller bearing designs are shown in Figures 1.20 and 1.21.The designs of cylindrical roller bearings are distinguished by the arrangement of the lips. Design NU (Figure 1.21b) has two lips on the outer ring, the inner ring being lipless. In design N (Figure 1.21a), the inner ring has two lips, the outer ring has none. Cylindrical roller bearings of designs NU and N are applied as floating bearings because the rollers can freely shift on the lipless ring in the axial direction. Cylindrical roller bearings NJ (Figure 1.20) have two lips on the outer ring and one on the inner ring; they can take up axial forces in one direction. Design NUP (Figure 1.21d) is installed as a locating bearing to sustain frequently reversing axial forces.
