The purpose of this study is to investigate residential characters and consciousness about housing environment concerned with earth housing, and to suggest basic data reflectible on the planning of earth housing. Residential characters and consciousness are investigated with the people lived in forty seven earth housings located in nationwide scale through interviews and questionnaire. As a result, it is shown that a reason of health like sick house syndrome, residential environments such as ventilation and lighting, site environment such as neighbor and greenfield are very influential elements to the consciousness of inhabitants. Meanwhile, approximation of residential area, the connection with public facilities including medical service, educational and commercial conditions, additionally, preparation of disaster and crime prevention in a viewpoint of safety are pointed out as relatively weak ones. It means that earth housing is not systematically fixed as a residential site because it is personally progressed by small number of peoples having different reasons. For the improvement of systematic housing environment, development and proposition of various model are needed on earth housing and its site.

Recently developed trenchless construction methods ensure stability for the ground settlement by inserting steel pipes along the underpass section and integrating steel pipes before ground excavation to form pipe-roof. This study is to confirm the reinforcing effect of pipe-roof by measuring lateral earth pressure acting on the underpass constructed by the STS (Steel Tube Slab) construction method. For this purpose, lateral earth pressure was measured at the left and right side of the pipe-roof after installing earth pressure cells. As a result, lateral earth pressure was measured with considerable reduction because the integrated pipe-roof shared surcharge. Therefore, economic design for the underpass could be expected by sharing design load by pipe-roof. In addition, construction cost was analyzed according to the design-load sharing ratio by pipe-roof. As pipe-roof shares design load by 40%, the total construction cost can decrease by almost 10% in the case of four-lane underpass.

Many countries have made their best to protect the earth from global warming and to find solutions for the reduction of carbon dioxide emittion and energy consumption. Especially, buildings have emitted over 40% of carbon dioxide against whole quantities emitted to the earth. Therefore, the reduction of carbon dioxide emitted from buildings require to save the earth environment. Energy consumption of buildings in Korea has reached 24% of total energy quantities, and energy consumption of collective housing has been continuously increasing. So, Korea government has also executed the Green Building Certification Criteria(GBCC). The GBCC evaluates the 8 types of buildings - collective housing, office, school, etc - to certificate the green building. In this paper, the evaluation items of collective housing in GBCC were reviewed to be used as the reference data for future revisions by the case studies. According to the results of this study, current version of GBCC requires additional revisions about the evaluations of energy consumption monitoring, commissioning and existing building.

This research aimed at showing an improvement direction in the future by analyzing the tendency to select a rural landscape housing and the characteristics centering around the data of the landscape-authenticated housing executed in Chuncheon City from 2005 to 2008. For 4 years, 25 houses in all were authenticated by Chuncheon City after being selected as landscape housing. As the result of analyzing the authenticated 25 housing, lots of landscape houses were located in natural green areas, and small-scale houses of $99m^2$ or less in the house size were preferred. The structures introducing the nature-friendly materials such as wood, yellow earth and clay continued to increase in the house structure. And in the selection of the authenticated houses, the landscape architecture and the harmony with the surrounding environment had a big effect on the selection.

It is very important for successful construction to estimate the soil volume conversion factor of domestic weathered ground accurately and reasonably. However, it is very difficult to quantify the weathering degree of weathered ground at the field, so that the soil volume conversion factor used in Korea is often dependent upon the standard of foreign countries. Besides, the soil volume conversion factor of domestic weathered ground has been rarely studied and the use and accuracy of the soil volume conversion factor have been questioned persistingly. This study suggests a simple but robust method for estimating the soil volume conversion factor and measuring the weathering degree reasonably, and attempts to establish the utilization of a soil volume conversion factor measurement system based on experimental and analytical results. We made relationship between electrical resistivity and weathering degree presented from weathering index obtained through laboratory tests using field samples, and an estimation method of in-situ weathering degree for granites and a calculation method of soil volume conversion factor using electrical resistivity. And also, we suggested the photogrametry measurement-equipment system for measuring the volume of cargo box and the application plan of stand equipment and RFID for calculating the earth volume and distinguishing buggies in order to design the measurement system for soil volume conversion factor applicable to the field. Ultimately, the Weathered Earth-work Management Program (WEMP) was developed, so field managers may easily obtain the information about earth volume and soil volume conversion factor at the weathered ground.

본 연구의 목적은 비개착공으로 시공되고 있는 지하차도를 대상으로 지하차도 상부 및 측벽에 작용하는 토압을 계측하여 압입된 강관에 의한 지보효과 확인을 목적으로 하고 있다. 근래의 비개착공법은 파이프루프를 형성하기 위한 강관을 압입한 후 강관과 강관사이를 철근으로 보강하고 모르타르를 타설하는 방식으로 침하에 대한 안정성을 보다 확보하기 위한 노력을 기울이고 있다. 이에 최근 적용되고 있는 UPRS(Upgraded Pipe Roof Structure)공법과 프론트잭킹(Front-Jacking)을 중심으로 강관 압입 후 강관에 의한 토압감소효과를 확인하기 위하여 지하차도 주변의 토압을 계측하였다. 그 결과 UPRS공법의 경우 지하차도에 토압이 상당부분 감소하여 강관보강에 의한 지보강성 효과가 발휘되는 것으로 분석되었다. 프론트잭킹 공법의 경우 지하차도 구조물이 외부에서 제작되어 압입되는 형식으로 강관을 보강시킬 필요가 없기 때문에 강관보강에 의한 토압감소효과는 예측한대로 발휘되지 않는 것으로 분석되었다.
