摘要
地下轨道交通的发展缓解了地面交通拥堵的局面,使得人们出行更加顺畅和快捷,促进了城市经济的发展。同时,地下空间得到发展和利用,提高了土地使用率,体现了建设节能减排型社会的总体要求。在不同地质条件下进行盾构施工技术研究,丰富了我国盾构施工领域的工程技术和施工经验,为相似工程地质条件下的盾构施工总结了施工参数。浅覆土、小净距、大坡度盾构始发技术是对盾构施工的全新体验和技术创新,施工不可预见因素多、风险大,施工安全标准要求高,郑州市轨道交通工程尚无先例与经验,以为郑州地区及相似地质工况条件下地铁施工提供经验和参考。
The development of underground rail transit has alleviated the situation of ground traffic congestion, making people travel more smoothly and quickly, and promoted the development of urban economy. At the same time, the underground space has been developed and utilized, which has increased the land use rate and embodies the overall requirements for building an energy- saving and emission-reducing society. The research on shield construction technology under different geological conditions has enriched the engineering technology and construction experience in the field of shield construction in China, and summarized the construction parameters for shield construction under similar engineering geological conditions. Shallow-covering soil, small clearance, and large-slope shield originating technology are new experiences and technological innovations for shield construction. There are many unpredictable factors, high risks, and high requirements for construction safety standards. There is no precedent for Zhengzhou Rail Transit Project. Experience, to provide experience and reference for subway construction under Zhengzhou area and similar geological conditions.
