Study on tree - root pile applied to foundation pit excavation support for existing factory plant under special geologic conditions 樹根樁圍護(hù)在老廠房?jī)?nèi)特殊條件下的施工研究
The authr has wosed back caiculation methd ha could calculate the safety fader of slope of sevetal rows root piles 根據(jù)反分析的基本原理,提出了反算法計(jì)算對(duì)于多排樹根樁加固邊坡后邊坡的安全系數(shù)。
It has hardly to get the method that adopting root piles to forrove slopes . root piles have been taken as ffiction pile , it have undertook not only horizontal load but also venical load 國內(nèi)外存在著諸多邊坡加固的措施,采用樹根樁加固邊坡的方法尚不多見,本文將對(duì)樹根樁加固邊坡的穩(wěn)定性進(jìn)行評(píng)價(jià)。
According to the characteristics of foundation pit and adjacent building and surrounding circumstance , some reasonable measures are given to protect the safety of adjacent building based on displacement control , such as prestressed anchor for limitation to lateral displacement of foundation pit , as well as root pile for foundation underpinning of adjacent building to increase its stiffness 摘要根據(jù)基坑開挖、場(chǎng)地地質(zhì)條件和鄰近建筑物的特點(diǎn),基于變形控制的考慮,采用預(yù)應(yīng)力錨桿限制基坑側(cè)向變形,通過微型樁對(duì)鄰近建筑物基礎(chǔ)進(jìn)行預(yù)托換加固增強(qiáng)其抵抗變形能力,保證工程順利完工和周圍建筑的安全使用。
