【提要】 因黃土地基濕陷沉降，某建筑物發(fā)生了傾斜沉降，經(jīng)過分析論證，采用靜壓樁托換實(shí)施頂升糾傾方案。設(shè)計(jì)采用400根托換樁，切割部分筏板基礎(chǔ)，減小頂升壓力。沿建筑物長度方向分三次一循環(huán)實(shí)施頂升，合理控制了頂升過程的穩(wěn)定問題。該糾偏加固工程實(shí)施順利，效果明顯，解決了地基濕陷的問題，達(dá)到了糾偏的目的，證明了該頂升糾偏工程設(shè)計(jì)的合理性，可以作為同類糾偏加固工程的借鑒。
【關(guān)鍵詞】 頂升糾偏 濕陷性黃土 托換樁

Abstract:Leaning and settlement appeared in a building for loess foundation settlement. The design method using underpinned pile for jack lifting and leaning rectification is adopted. The design had used four hundred underpinned piles, and a part of buoyant foundation was cut. The jack lifting had three times for a circle, and the stable problem of jack lifting was controlled. The engineering was finished successfully, and it had important reference meaning.
Keywords:jack lifting;leaning rectification；loess soil；underpinned pile
