Dynamic Responses of a Coupled Tunnel with Large Span and Small Clear Distance under Blasting Load of the Construction of Transverse Passage

Round 1

Reviewer 1 Report

Dear Editor Journal of Applied Sciences

The article entitled “Dynamic responses of a coupled tunnel with large span and 1 small clear distance under blasting load of the construction of 2 transverse passage”, have useful scientific information. But, paper in present format require to minor revisions. Specific remarks are as follow:  

1- Important results should be expressed quantitatively in abstract.

2- In terms of grammar, paper should be re written again.

3- Which method have been used in numerical by ABAQUS? Explicit or implicit? It should be described in text.  

4- In terms of soil-structure interactions, numerical analysis have been performed? It should be described in text

5- Why velocity of vibration has been considered in numerical analysis? As, in terms of nature, force is different from the speed of vibration. Velocity can be checked in elastic space and Force can be evaluated in elastoplastic and plastic space. It should be described in text.

Best regards

Reviewer 2 Report

1. The research gap and research significance of this manuscript is not clearly presented.

2. Lots of technical parts in the modelling analysis are missing, such as the rationale of choosing ABAQUS, mesh density analysis, model size optimization, etc.

3. There is no discussion part.

4. The conclusions of this manuscript are too general, more specific and quantitative conclusions are needed.

5. All the figures should be lift for clearer ones.

Too many long sentences makes this manuscript hard to read.

Some typos should be corrected.

Reviewer 3 Report

The marked suggestion in the attached paper may be addressed for improvement of the paper

1. abstract should include the results of the study

2. Line 108: Show the researchers defined limits of vibration with respect to damages

3. line 146: Pronoun should not be used

4. how structural features of rock mass was incorporated in overall model

5. keep same terms in equation and text

6. line 187: needs reference, also more explanation is required for equation 3

7. table 1: use standard nomenclature in table, need revision

8  Fig 4: show the actual drilling and firing pattern with dimensions and blast hole section

9. Use blast hole in place of bore hole

10. Fig.5: how detonation sequence was considered for calculating impact pressure, what is the impact of MCPD on pressure

11. line 267: ?? table permissible limit may be incorporated

12. line 272: blast wave frequency ?? to be given

13. line 302: what is the tensile strength of the lining

14. Fig 12: trial blasts data requires to understand the PPV vs distance 

15. Conclusions: Give in brief with data as per the research outcome

Reviewer 2 Report

The quality of figures still can be improved for better understanding for readers.

Polish the language is still needed.
