Numerical Simulation And Deformation Control Of Deep Foundation Pit Support Of The Experimental Building In Northeastern University At Qinhuangdao

Society is in development,the city is in construction,enterprise has used the field increasing by in addition with the fact that the population ceaselessness increases by, city land for construction has been falling gradually,ceaseless springing up of tower has produced the magnanimous deep base pit project. Increasing by because of deep base pit project, before various geology condition and the complexity to varying degrees building an environment on every side having appeared. Such deep base pit project working and shoring are related to self base pit safety not only,the building weighs also to adjoining.The main body of a book actual construction project of synthetical experiment of union Northeast University at Qinhuangdao branch school building, take owing a deep project base pit shoring a project as object of study, by the fact that inspection of the scene of a crime and interior influencing factor such as vicinity building and geology environment testing the data and the project are in progress to the project study analytical. Have calculated , have designed and have carried out systematic analysis and calculation on the deep base pit scene and the environment monitoring in the process being under construction to the choice owing a deep base pit project the scheme carrying out a shoring,the project excavates the contrast carrying out the numerical value simulation analysis and monitoring result with the scene with the shoring by the fact that finite element method MIDAS-GTS analyses a software to deep base pit , verify rationality and security that the shoring designs to the base pit.The geology condition and environment first, analysing and studying a construction site detailedly is not bad reach, geology condition is complicated , there exist a two layer of groundwater in inner since excavating range in the base pit, the grit that existence relaxes moulds the state viscidity soil tier with the stream, and the periphery building is concentrated , adjoin to base pit border. Have divided the area 3 studying according to base pit current situation has carried out a side slope , again, have analysed and have studied to the go along studying area parts for one by one, the scheme carrying out a shoring on the base pit optimizes choice.Secondly.to the base pit shoring ascertaining the queen, the scheme adopt equivalence Liang Fa to carry out shoring physical design secretly scheming against, and carries out stability checking calculation on the design plan; Draw support from finite element method MIDAS-GTS building the soil body model, the process simulating a base pit excavating construction pulls shoring pole deformation mechanism to base pit anchor , the pole is equivalent to displacement , the pole body in bending regulation , the axis force, prestressing force rockbolt strain.axis force and soil body plasticity deformation have carried out the building studying and simulating the body and vicinity calculating the safety pulling shoring pole construction with deep base pit anchor monitoring comparative analysis, being excavated with the shoring to base pit soil detailedly deformation effect.In short ,the simulation analysis and the scene have monitored result by numerical value , have ascertained rationality and reliability that the deep base pit shoring scheme chooses further , have suggested that two kinds new construction handicraft are a time limit for a project to being a project's turn to be able to can get under the wire in limited time limit for a project have economized project cost being unable to cut short , have made the choose in safety , economy , rational angle of deep base pit shoring scheme further rich embody , provide the effect drawing lessons to the project each other, similar and being related to in the days to come but consult.
