The Application of the Value Engineering Theory in the Optimization of the Foundation Pit Supporting Scheme

摘要

The foundation pit engineering is a complicated system engineering. The reasonable foundation pit supporting scheme is the key to ensure the construction quality of foundation pit engineering. The trait of the foundation pit engineering includes the strong regional trait, relatively large risk, strong personality, high accident rate, a very comprehensiveness, high quality requirement and so on. The type of the foundation pit supporting scheme are as follows: the slope excavation, the soil nailing wall, the steel sheet pile support, the continuous underground wall, the reinforced cement soil retaining wall, the row pile support, the deep mixing pile retaining, the bolt support, the composite supporting structure. The value engineering is the modern management technology of combination of technology and economy. It is a effective method to reduce the cost and improve the economic benefit. The application of the value engineering theory to optimize supporting scheme can reduce the construction cost and improve the economic benefit. The engineering example shows the application of the value engineering theory in the optimization of the foundation pit supporting scheme.
