在暗挖通道施工过程中,为保证侧上方百年历史古建筑物（属于危楼）变形可控,采用地表复合锚杆桩将暗挖通道和建筑物隔离、洞内深孔注浆对通道拱部粉细砂层进行超前加固的复合技术。通过对比监测统计数据,采取的复合加固措施达到了预期的目的。对比其他隔离、注浆加固措施,所选措施受场地制约小,更适用于城市地铁施工。
在暗挖通道施工過程中,為保證側上方百年歷史古建築物（屬于危樓）變形可控,採用地錶複閤錨桿樁將暗挖通道和建築物隔離、洞內深孔註漿對通道拱部粉細砂層進行超前加固的複閤技術。通過對比鑑測統計數據,採取的複閤加固措施達到瞭預期的目的。對比其他隔離、註漿加固措施,所選措施受場地製約小,更適用于城市地鐵施工。

A horizontal gallery of a Metro station passes below a historic church.In order to control the displacement of the historic church during the construction of the horizontal gallery,composite anchor piles are installed from the ground surface to separate the historic church from the horizontal gallery and deep-hole grouting is executed from inside the tunnel to consolidate the fine silt sand strata at the tunnel crown.The monitoring results show that the composite consolidation measures taken are effective.The measures taken are superior to others in terms of site requirement and therefore are more suitable to be used in urban Metro construction.
