Research And Analysis Of Pump House Ledger Wall Of The Vertical Axial Flow Pumping Station With Elbow Type Inlet Passage By FEM

The large-scale pumping station ledger wall and the flow channel in the geometry are a complex spatial structure. Each kind of load distribution also very is often complex. The structure system also must satisfy the request which the flood prevention guards against infiltrates. The geometry characteristic and the load characteristic have the big difference with the theory of elasticity in plane strain condition. The present dam and the pumping station design standard recommendation use "the truncation strip law" namely carries on the computation along the fluent direction interception unit width ledger wall can be considered as transverse elasticity foundation beam or the frame. In the soft soil ground the dam, the pumping station ledger wall structure computation use "the truncation strip law" carries on. Has in the certain degree approximate.This article unifies the northward rerouting of southern river Tai er zhuang pumping station the structural design, Uses the space finite element analysis,Really has simulated the actual structure. The main work is as follows.1. Introduced the high accuracy finite element auto-adapted algorithm and its in the dam finite element analysis application emphatically.2. Establishes the Tai er zhuang pumping station ledger wall the space model, And obtains in constructs the time, the design transports in the departure date two kind of basic loads combinations situation the finite element solution.
