Title Design of an excavation bracing system of a Times Mansion
Abstract
In this paper, the main content is a Design of an excavation bracing system of a Times Mansion. Proposed site is located in qixia district in nanjing xianlin , jiangsu weft road north, 312 national road south. Venue for hilly ~ slope, have been filled in the live, overall relatively flat terrain. North of west, foundation pit away from the water landscape about 15 meters; On the east side of yuan road, about 60 meters, the south about 20 meters away from the park road, determine the foundation pit engineering safety level to level 2. According to the situation of site soil and surrounding environment, design and construction of foundation pit excavation rainfall drainage should be considered and foundation pit excavation and supporting.
This article uses the manual calculation and the Lizheng F - SPW6.0 computer software, in accordance with the construction of foundation pit supporting technology regulation (JGJ120-2012) for design and calculation of the supporting system. By querying the related specification and the project examples,I completed check precipitation and monitoring solutions.
