Research On Numerical Calculation Of Foundation Pit Support By Row Of Piles

Currently there is a lot of category of foundation pit protect structure, how according to effective demand choice accommodation of protect structure combine reasonably assurance protect structure of the parameter still keep being a hard nut to crack. Because row stake-the steel prop up to protect structure to have environment influence small, the strong etc. advantage of the geologic strata adaptability, drive extensive used for foundation pit to protect engineering in. This text draw up with row stake-the steel prop up to protect structure for research object, thorough research its structure be excellent to turn a problem. This text first introduction foundation pit protect of category, break form and its function and characteristics, analysis foundation pit protect existence of some problem. Detailed analysis soil pressure calculation theories with deep foundation pit protect structure design calculation theories, and to tradition calculation method and modern calculation the method carried on comparison. Study deep foundation pit protect structure excellent turn design method, detailed elaborated the foundation theories of m calculate way and realization technique. The m calculate way is that the overall situation be excellent to turn of search calculate way, it make use of the championship be inferior to discard of nature the choice come to instruction and study with assurance search a direction. Compared with the tradition calculate way method, m calculate way to solve of excellent turn a problem don't have too many mathematics request, apply scope more wide, suitable for solve foundation pit to protect excellent turn design problem. Study cross all a rate, variation all a rate, community scale, evolution algebra's etc. change quantity of selection problem, establishment according to 'm' calculate way of row stake-the steel prop up to protect structure excellent turn design of mathematics model, combine consideration cent step to open to dig an increase of effect quantity calculation method, pass decision to change quantity, target function, control condition really sign, success realization row stake-the steel prop up to protect structure of the parameter be excellent turn design.This text protect to the row stake structure of calculation the theories carried on more overall, system of analysis and research.First, consideration foundation soil of become a layer, according to often differential calculus square distance of standard basic solution, deduced row stake to protect dint inside the structure and transform of calculation formula, and turn its procedure. Immediately after combine engineering solid example, verification calculation function and possibility of method and procedure, and detailed analysis influence row stake protect dint inside the structure and various factor for transform. Secondly put forward a row stake a steel to prop up the concept that the space be in conjunction with a function, establishment row stake a steel prop up coefficient calculation model and method. End, combine engineering solid example, rightness actual engineering of row stake protected structure to carry on a design calculation, calculation result can be provided as engineering design and construction reference.
