沉管法隧道设计过程的方案比选及投资估算

Scheme comparison and investment estimate during tunnel design with immersed tunneling method

结合实例对沉管法隧道设计过程中各阶段和各部位的设计与施工方案的经济性和可行性进行比选 。

Combined with examples, this article performs an economic and feasible comparison among the design and construction schemes of each location in different phases of the tunnel design with the immersed tunneling method before bringing forth the problems calling for attention of the tunnel with immersed tunneling method in course of design and also the determination method of engineering investment estimate for the tunnel with the said method.
