Seepage Actions and Their Consequences on the Support Scheme of Deep-Buried Tunnels Constructed in Soft Rock Strata

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

In this paper, the authors carried out analytical analysis to investigate the stability of deep soft rock tunnels under seepage application. Generally, this work is interesting and could be considered for acceptance after a few modifications. Some advices is presented as follow,

1. What is Mogi-Coulomb strain criterion? The criterion should be stated in the main text. 

2. Figure 1 is confusing. The red pin on the map should be marked with the project name. 

3. Figure 3 is confusing. The authors should explain why the horeshoe tunnel is modelled by circular tunnel.  In the picture,  it is obvious that the cross-ectional areas of the tunnels are not equal.

4. The surrounding rock is divided into two zones. Do the authors ever concern the grouting effect outside the tunnel lining? The grout layer works significantly on waterproofing. The performance of the grout around the tunnel can be referred to in Ref [1].

5. In the discussion, the in-situ measurements should be added for comparison. Without it, the case study is not that meaningful.

Comments and Suggestions for Authors

I would be a litte more precise in the monitoring techniques and add the water / humidity distribution mapping as a main monitoring system
