摘要
Abstract
A full 3D finite-element aseismic analysis model is developed for foundation-pumping station structure of Suining pumping station II of the east route south-to-north water transfer project,a large-scale pumping station on soft foundation in a meizoseismal area.Through analysis of computations and comparison of alternative schemes,a reinforcing scheme that adopts underground continuous wall foundation of an integral structure layout and anchor bolts-bored piles,is recommended,and a scheme of prestressed anchor bolts being tensioned at the construction stage is proposed to ensure stability of the deep foundation pit.The prestress of anchor bolts will be released after completion of the construction,so that the whole pumping station,maintenance room,control room and underground continuous wall can form a similar half-buried underground structure.Thus the key aseismic technical problems of this pumping station are completely resolved,and the proposed methods and results provide a technical support to the aseismic design of Suining pumping Ⅱ and the other pumping stations with soft foundation.关键词
