  • Excavation in a big city is different from excavation in a local area because construction methods and stability are directly connected in a loss of life. Especially, estimate of rock mass slope stability is excuted by more detail and safty work. In this study, we are made reserches in rock mass slope stability and safety method that the slope is closed by elementary school in a big city. The result of many field study and numerical analysis is shown up direct reinforcement used to anchor.

  • This paper represents a survey of a variety thresholding techniques including both global and local thresholding. Several thresholding methods are examined in detail to evaluate their performance based on a given set of test images. We also attempt to evaluate the performance of several thresholding methods for construction field documents image recognition system using a broken line structures, broken symbols and text, blurring of lines, symbols and text, noise in homogeneous areas measure as a criterion functions.

  • This paper presents the results of instrumentation of a two-level of soil-reinforced segmental retaining wall. Instrumentation items include the lateral wall displacements and the geogrid strains at several locations. The instrumentation is still long carried in order to examine long-term behavior. The result indicate that the upper wall has a significant effect on the behavior of the lower wall doubling the wall moved. The wall also exhibits significant post-construction movements that had ceased several months after the wall completed. The implication of the findings from this study was discussed in great detail.

  • Without any doubts, the characteristics of regional, lines and lines section have dominating effects on the railway design of rectification to linear alignment. There are basically many types of characteristics: a) geological condition b) operation plan of lines and lines section c) condition of lines facilities level. The conventional deign method were exclusively used to railway design and construction. However, lot the optimum design, the more detail study are required.

  • This paper presents in detail the construction of an unsolvable Thue system on two letters. The approach employed consists of first constructing a Thue system ${\Gamma}$ on n letters whose decision problem is recursively unsolvable. Then along the lines suggested by Davis [1], a combinatorial system ${\Gamma}^*$ whose alphabet-consists of two letters is constructed whose decision problem is recursively solvable if and only if that for ${\Gamma}$ is.

  • Chinese construction companies take major roles gradually in the global construction market. Chinese construction companies performs well-organized project execution by the construction related professionals based on the domestic education and qualification system. The purpose of this study is to analysis the characteristics of professional qualifications for constructor and quantity surveyor in China. The result shows that qualification systems of constructor and quantity surveyor are well classified in detail and operated by government. Each qualifications require broad and defined knowledge structure together with practical experiences. The research result will open the further research of Chinese construction related qualifications in the ways of more specificity, expertise, and practicality.

  • In Korea, currently 10 local governments have completed the construction of the 3D Land Geospatial Information, since the pilot project started in 2004 and many other local governments are additionally constructing the 3D Land Geospatial Information. Technical Guidance for the 3D Land Geospatial Information has made out the construction methodology and concept of the ordinances in 2006 by the basis of the research results of the pilot project for the 3D Geospatial Information construction in 2005. But the result that applied the existing 3D Land Geospatial Information of the local governments, many problems rearing up on the methods and expression accuracy of the 3D Land Geospatial Information. This research analyzed and derived problems of established guideline for the zero-defects construction of the 3D Land Geospatial Information and it is aim at the present standardized criterion of the reestablished and method of the 3D Geospatial Information construction items. Improvement scheme of the 3D Land Geospatial Information is considered to be contribute to the standardized good quality of 3D Land Geospatial Information construction and its application.

  • Globalization of business activities and the market is making intern ational movement of capital much freer. Therefore the introduction of global standard is inevitable. Each and every country has had its own standard which restrain free exchange and cause misunderstanding and conflict between countries. A country or a company which is not capable of meeting the global standard can not be accepted in the global market. Consequently, it will eventually be left behind. It is right to say that countries and companies should accept the global standard and abide by it to survive in the competitive global market. The following preface which was introduced in the international conference co_organised by BAC, FTCTC and Tsinghua University in May, 2004 shows a timely movement for the globalization of construction business. *B A C, Beijing Arbitration Commission *FTCTC, The FIDIC-Tsinghua-CNAEC Training Center *CNAEC, China National Association of Engineering Consultants Introduction, As arbitration becomes more and more popular in the ways of alternative disputes resolution all over the world, the BAC is devoted to promoting international arbitration in China. As FIDIC contracts constitute an accepted point of reference for international construction contract, the BAC, characteristic of construction projects, is willing to facilitate the FIDIC contracts as the referred construction contracts in China. In order to carry out its purposes, the BAC, together with FTCTC is going to convene for discussion of dispute resolution and arbitration of international construction projects. FIDIC, construction contract management guide, explains arbitration as the ultimate dispute resolution method. The detail of FIDIC will be suggested in this essay.
