［摘要］針對某在建短肢剪力墻結(jié)構(gòu)住宅傾斜情況進(jìn)行了檢測和分析，在確定基礎(chǔ)不再發(fā)生不均勻沉降的前提下，制定了在地下一層切斷剪力墻、繞旋轉(zhuǎn)軸頂升糾傾和連接的糾傾方案，頂升力由采用統(tǒng)一供油和控制系統(tǒng)的液壓千斤頂承擔(dān)，比抬升基礎(chǔ)的頂升力減小了30%，旋轉(zhuǎn)軸墻體用于承擔(dān)全部水平荷載作用，安全儲備高；方案不擾動地基土持力層，地基的附加應(yīng)力和變形小。該工程主體結(jié)構(gòu)已施工完畢，地下一層剪力墻處于高應(yīng)力作用下，設(shè)計了一套完整的高應(yīng)力作用下頂升剪力墻的裝置，包括夾持鋼梁、對穿抗剪螺栓、斜撐等，有效傳遞了剪力墻較大的豎向壓力，保證了糾傾期間結(jié)構(gòu)穩(wěn)定性，糾傾效果良好。還提出了頂升期間建筑物的監(jiān)測要點，以及施工期間結(jié)構(gòu)安全預(yù)警值和施工結(jié)束標(biāo)志，充分保證了頂升期間結(jié)構(gòu)安全。

Abstract:Based on the detection and analysis of the inclination of a short-limb shear wall structure residence under construction, and on the premise that the foundation no longer has uneven settlement, an inclination rectification scheme was formulated by cutting off the shear wall in the first floor of the underground, lifting and rectification the inclination around the axis of rotation. The lifting force was borne by the hydraulic jack with unified oil supply and control system, which was 30% less than the lifting force in the jacking the foundation. The axis of rotation wall was used to bear all horizontal loads, with high safety reserve; the scheme did not disturb the bearing layer of the foundation soil, and the additional stress and deformation of the foundation were small. The main structure of the project was completed. The shear wall on the first floor of the underground was under the action of high stress. A complete set of devices for jacking the shear wall under the action of high stress was designed, including clamping steel beams, cross-through shear bolts and diagonal braces, which effectively transferred the greater vertical pressure of the shear wall, ensured the stability of the structure during the rectification period, and the inclination rectification effect was good. The monitoring points of the building during the jacking period were put forward, as well as the structural safety warning value and the construction end sign during the construction period, which fully guaranteed the structural safety during the jacking period.
Keywords:short-limb shear wall structure; high stress; jacking technology; inclination rectification; stability of structure
