Soil nailing as an economical and reliable , quick and easy retaining technology in Hefei area deep excavation of the high-rise building construction in recent years has been widely used . As the the Hefei area is located between Jianghuai expansive soils are widely distributed in expansive soil distribution , when the excavation depth exceeds the depth of expansive soil , expansive soil water swelling , dehydration shrinkage characteristics will slope ( pit ) stability poses the most direct threat . This article by theory with practice , study of the theoretical calculations and the actual construction of the soil nailing . Instance of the two projects designed to calculate the soil nailing the practical application of the expansion of the land area in Hefei . Practice has proved that the soil nail wall technology for expansion of land area Pit Supporting effective , its unique active reinforcement mechanism complete to maintain the structural integrity of the soil and the original stress state , thereby effectively curb the swelling potential of expansive soils , the design and construction of conventional . Foundation construction , construction monitoring is very important , the implementation of dynamic information management , timely adjustment can make construction management more scientific and reasonable .
