摘要
隧道近阶下穿对既有构筑物产生扰动,威胁既有构筑物的安全运营.根据具体工程案例,提出隧道下穿高压电塔施工方案,并揭示高压电塔的水平位移和竖向沉降规律.研究成果为隧道下穿工程提供参考,保障隧道上方临近结构的安全.
Abstract
When an existing structure is underpassed by a tunnel at close range,the structure will be disturbed and its safety operation will be threatened.Based on specific engineering case,tunnel construction measurements are proposed when high voltage towers are underpassed.At the same time,rules of horizontal displacement and vertical settlement of the towers are revealed.The research results can provide references for tunnel underpassing engineering and ensure the safety of adjacent structures above the tunnel.
