摘要
介绍了国内首次双圆盾构下穿原水管渠工程的特点和采取的调整盾构施工参数、对土体注浆等有关措施。施工结果表明,处理措施是有效的,原水管渠的扰动位移始终保持在允许值20mm以内。
As for the first case of double circle shield tunneling under raw water culvert in our nation, there are many difficulties to be overcome. Based on the characteristics of the project, construction technique like adjusting construction parameters of double circle shield and consolidating the ground are adopted. The results of the construction show that the countermeasures are efficient.
