Deformation Monitoring and Environmental Protection for Deep Foundation Pit Engineering

Abstract

For researching the influence of excavation constructing to the environment, we took many measures to monitor the deformation of retaining structure, underground pipelines, groundwater-bit and surface cracks, according to the actual situation of the engineering. Obtained the deformation discipline and force characteristics of the excavation, as well as the discipline of influence. From the results of monitoring, it showed that monitoring is the key to the informative construction of the excavation. Analysis the result of monitoring dynamically, can guide the construction, and adjustment the design. From the engineering, it might have large influence to the environment even the design was reasonable and the retaining system met the security conditions. So, a economic and fitting, security and reliable technology plan for protecting the buildings, roads and pipelines close to the excavation is necessary.
