건축물 지하층의 부력방지 시공법 선정에 관한 사례연구

Abstract

This study discussed the theoretical review on the Uplift Force Method due to the presence of the underground water and also executed the comprehensive comparison about its constructability, economy and stability, etc. Through the analyses of ongoing applications more specifically, I presented the optimal Uplift Force Method by studying many Uplift Force Method based on the mathematical principles, focusing on the presentation of the blueprint toward the future city development with infinite potential about making the underground space. The method of study was investigated by comparing and analyzing the general Uplift Force Method using the re-tensioning permanent anchors applied at OOProject site located in Kimhae, Kyungsang-namdo province, and another Uplift Force Method using the Mass Concrete applied on many construction sites. Eventually, I wanted to present the optimal Uplift Force Method. The results of this study are as follows; 1. Stability The Uplift Force Method using the permanent anchors was the most favorable to the stability of the building in terms of the adaptability to the building size or to the underground inconsistency, the response to the variable load conditions and waterproof function. 2. Constructability The Uplift Force Method using the permanent anchors did not excel other construction methods in the Constructability. However, it was possible to keep the consistent quality with load-bearing capacity and standardized units made in factories. 3. Economy The initial investment cost of the Uplift Force Method using the permanent anchors was found to be overly inputted. But I expected the cost-saving effects from the additional cost-saving effects during the post-construction maintenance and from the durability period of the buildings.
