The contiguous construction in downtown area requires an appropriate substructure construction method since it results in the insufficient working spaces and frequent public resentment by noise and vibration. In particular, Top-down method usually is applied for downtown construction, and followed by several difficulties in casting the slab concrete for substructure. In this study, we focus on the improvement workability for substructure construction.

The Seoul Subway Line 4 crossing downtown diagonally constructed in February 1980 and opened on October 11, 1983. The line 4 is thus able to link southern and northern parts of Seoul with the downtown as well as with the Seoul outskirts. More than 810,000 people use it everyday. Line 4 was constructed like Line 1,2,3 with ballast track system causing much maintenance cost gradually and espicially much public discontent due to wheel and rail contact noise by railway viaduct with sharp curves. CWR on railway viaduct with sharp curves, 180m$\leq$R$\leq$300m, hasn't been designed and constructed ever in domestic. Therefore in order to reduce noise and vibration caused by interaction between wheel and rail the possibility and the methods of CWR(Continuous Welded Rail) on railway viaduct with sharp curve less than R300 will lead it to the maintenance free system.

The purpose of this study is to analyze the occurrence characteristics of vacant spaces in the old hillside residential area, focused on 7 areas surrounding old downtown in Busan. This study suggests 3 stages of analysis as following. First, after the overall site survey on the vacant spaces in 7 old hillside residential areas in Busan, this study identifies the difference of types of vacant spaces according to each area. Second, based upon precedent researches, this study set up 3 perspectives and 9 analysis indices to investigate the areal characteristics of vacant space occurrence. Third, through the GIS analysis on the vacant spaces, this study tries to analyze the physical, commercial and social/institutional conditions of the areas in order to disclose the areal characteristics of vacant spaces occurrence.

This study is designed to examine characteristics and types of basic landscape design established by 7 local governments in Jeollanam-do and its availability as the index of landscape administration and present a guideline with view landscape plan of local governments. The results of this study are described below. In case of view landscape, while Korean cities have not many historical assets like landmark, they have locational characteristics with mountain or coast in the center or surroundings of downtown. Therefore, since view landscape has many cases of restricting individual property rights as well as having a value as public property of city which makes recognition of sharing city, it is very sensitive problem and establishing guideline of it is needed. But, it was found that view landscape plan of local governments established location of view spot with the nature of relief viewing downtown or coast from high spot. Selection of viewing objects in view plan require deciding an object as the public property of city and big cities require selection from the zone and small cities must select 1~2 spots from the viewpoint of whole downtown. 3~4 view spots of middle and distant views which makes city community centering around the subject of view must be selected through enough discussion and in case of natural landscape, View shaft or visible rays require setting of range that 30% of viewing objects is seen. View spot or viewing objects should be selected over twice as extra spots through public hearing and civil participation as the process.
