Analysis Of The Settlement Charcter And The Commonly Used Forms Of The Multi-storoy Building Foundation In Wenyan

Soft soil foundation settlement is building on soft earth foundationproblems. Based on the construction in the building to build the system ofsettlement observation, using a large amount of measured data ofsettlement characteristics of analysis, research of various factors on thedeveloping regularity of settlement influence, as well as the settlementdeformation law of development with time, in theory and practicalapplication is very important.In this paper on the Wen weir area multi-storey buildings on thebasis of research has been to hear weir area building main forms the basisfor the pile foundation.Because the pile foundation can better overcomethe foundation bearing capacity is insufficient and uneven settlement ofpile foundation have been problems, Wen weir area building mostcommonly used foundation form. Through the collection of Wen weir in different type of pile framestructure building system of settlement observation data, obtained a largeamount of first hand materials.According to the measured data, thecommon used hyperbolic method, logarithmic curve method, and basedon the hyperbolic formula regression analysis three kinds of prediction offinal settlement of pile foundation construction method on finalsettlement and settlement course is calculated, and compared the result ofcalculation method of pile foundation code.Comparison of measuredresults, hyperbolic method the predictive value compared withapplication of logarithmic curve method results.Based on the theory ofthe hyperbola regression analysis method, the calculating the finalsettlement value and the measured settlement than the other two methodsmore closely, this method can be used to achieve good results, and thepile foundation code calculated results are generally too large.By using the regression analysis of the measured settlement data tocarry on the analysis, obtained the settlement of pile foundation ofdevelopment law of curve and regression trend curve.The pile foundationsettlement not only with the external load is applied load speed; Wen weirbuilding pile foundation settlement stability time is about the main capwhen the time required for1.5~2.5times the main conclusion.Andsummarizes the concrete cast-in-place pile, concrete bored pile andprestressed concrete pipe pile settlement rules and characteristics of settlement, get some help engineering practical conclusions.
