摘要
盾构掘进机是在软弱地质条件下安全施工的有效机具,在我国已有30多年的历史。但由于其巨大的一次性投资及高昂的使用成本,使其在我国的推广使用受到极大地制约。通过对我国盾构掘进机使用情况的调查,提出只有依托国家的重点工程项目,大力开发研制国产盾构掘进机,才能稳步发展我国盾构掘进机事业。
The shield TBM is regarded as an effective tool during construction under soft geological condition, which has a history of 30 years in China. But the use of shield TBM in China is seriously restricted due to its high investment and cost. Through investigation of the use of shield TBM in China, this paper puts forward a proposal of researching and developing the home shield TBM in great efforts with the support of national key projects.
