Study On Program Of Anti-Sliding Pile Analysis And Calculation

With the rapid development of some nationalindustries, such as cities, traffic, mine,environmentalprotection etc, it becomes increasingly important toadminster landslide. Recently, anti-sliding pile regardedwidely has turned into a dominating means ofadminstering landslide geologic disaster and developsrapidly in homeland and abroad with great adaptabilityand sliding strength. Besides, it is possible to driveanti-sliding piles simultaneously and short the timelimited for a project.A lot of sophisticated calculate doesn't avoid in thedesign of anti-sliding pile and the data calculation isterribly huge. Fortunately the calculated results will beaccurated and credibled by computer .So large labourwill be saved.Because the science of computer has beendeveloped rapidly, even faster than any commonsubject recently. Not only the influence occurred bythe continuously development and updating of thecomputer technology should be concerned , but alsothe theoretical knowledge of this subject should becombined well.However, it is investigated that the presentcalculated program isn't systematic or doesn't combineintimately with the theory of this subject. What's morethe key of calculated method is excessively one-sidedand simple.Therefore, it is necessary to study how to designand calculate the anti-sliding pile. According to the statenatural science foundation item"the study on nonlineardistribution feature of interaction force betweenanti-sliding pile and surrounding rock"(40072086) thispaper brings forward the program of anti-sliding pilewhich makes the calculator fast and systematic.This paper makes an analysis and summing-upabout the design of anti-sliding pile on the base of alarge of informations . The calculation of internal forcein anti-sliding pile body is the key in program.Thewhole calculation program is studied further based onthe calculation of internal force which is the pragramcenter. One hand, it is necessary to calculate the slidethrust before counting the internal force of pile body, onthe other hand ,the calculation of structuralreinforcement is an essential procedure after theinternal force calculation. Hence, there are three partsin the program of anti-sliding pile as the following: thecalculation of slide thrust, the internal force calculationof anti-sliding pile, and the calculation of structuralreinforcement.While the essence of the calculation module is slidethrust by the use of the transfer coefficient. So a goodand easy operational interactive interface is providedfor the users.The shear strength index of slide surfaceshoulded be definited during using the commontransfer coefficient. But the adjustability of the shearstrength is very complex. While it comes to be true toadjust automatically using a software and relevantarithmetic.This kind of calculation module includes manyfunctions: logging tapered parameters of land-sliding,inputting the engineering property parameters of thegliding mass and slide surface, inversing the shearstrength of land-sliding, searching automatically theposition of piles, calculating the slide thrust, the displayof calculated result and so on.The internal force calculation module of anti-slidingis the core of all the program, which calculates the pilebody internal force, using mainly the two-parametermethod and draw relevant sketch map of the internalforce and provide essential materials for the design ofthe anti-sliding pile.The cantilever pile is applied to calculate theinternal force of pile body in this program. It is easy tocalculate the slide thrust and the resistance of soil infront of the pile, which occurs in the loaded sector ofpile body; while in the anchored sector of pile body,there is the resistance of soil around pile, which iscarried out by using two-parameter method.At present, people have started to attachimportance to the two-parameter method, which is afrontal technique in the research of the internal forcemeans of anti-sliding pile. This method can simulatecorrectly the interact between piles and soil .So it isapplied in many ascepts. The practicability is verywidily.This paper makes an preliminary study on thepresent calculation method of the anti-sliding pileinternal force, then deduces the theoretical formula ofthe two-parameter method and the analytic result.Using the calculation program of anti-sliding pileinternal force the resistance calculation of the stratumin front of piles, the factors of anti-sliding pile body , theforce in pile body can be easily calculated. The resultand the sketch maps will be easily displayed..The calculation module of the structural distributedsteel is to account the structural reinforcement of pilebody.Anti-sliding pile can be calculated as the member inbending, so the flexural torque and shearing force arethe main internal forces of pile body section. Whenchecking computation of the pile body section, theshear strength of oblique section shoulded beconsidered as well as the right section. Besides, thestructural distributed steel also can be calculatedaccording to the criterion of concrete structural design(GB 50010-2002).This program of anti-sliding pile analysis andcalculation integrated highly the whole design ofanti-sliding pile and calculated the force in the pile bodyusing the two-parameter method. And the program...
