Deformation Analysis Of A Deep Excavation Supporting Structure In Handan

The pile anchor supporting structure is made up of retaining pile and anchor whichgrapple in the stability soil outside the foundation pit slip surface. Under this structurecan support a relatively large and complex surroundings Pit Slope excavation is notallowed in the pit depth and unsuitable for the set of circumstances supportingexcavation conducted support. This broad support in the form of universality, and lowsupport costs and lower construction technology requirements are such that it has agood prospect in the future excavation projects. But then the ideal support form at thetime of excavation will be more or less affected by the distortion caused by earthexcavation. Excavation pit can not only make the supporting structure itself has a largedeflection, the supporting structure affect security and stability, but also could threatenthe surrounding buildings and underground pipeline safety, so fashionable to beconcerned about excavation pit excavation caused by the deformation.Based on the research results of previous studies, this paper introduces thecalculation method of pile-anchor retaining structure deformation and deformation ofthe pit caused by various factors, and proposed excavation deformation control methodand control standards.First, the Handan City to a specific excavation described in detail through the list,mapping the way pit deformation monitoring results were consolidated, and monitoringdata were analyzed to characterize features.Then calculated the old norms supporting piles deformation in various operatingconditions, and the old norms of the calculated difference conducted a brief analysis;Also calculated using the old norms supporting structure in a different anchorprestressing, overloading and different pit design parameters to select differentconditions for each case of deformation of supporting piles.Finally, this article will be calculated using the old and the new norms andmonitoring the results of a comparative analysis of the results. Concluded that theresults calculated in accordance with norms and values are more in line with themonitoring.And if the blind pursuit of the construction pit and not strictly in accordancewith the construction progress of the construction specifications for construction, excavation will lead to large deformation, so in the specific construction must complywith design and construction standards to ensure a solid supporting structure, safety.
