Study on Vertical Load Distribution of Pile Group–Liquefied Soil System under Horizontal Seismic Environment

Round 1

Reviewer 1 Report

1. There is not clear comparison between laboratory results and simulations findings. 

2. Parameters like variations in pore pressure, displacements, increment of stress are not shown or discussed due to cyclic loading application. 

3.  Changes in friction are simulated but not compared with laboratory test model.

Reviewer 2 Report

This paper investigated the vertical bearing capacity of the pile foundation - liqueffed soil system under simulated horizontal seismic forces with the shaking table test and three-dimensional ffnite element in the MIDAS GTS software. The load borne by the pile top was studied under horizontal earthquake with a certain vertical load, different pile spacing and different vibration time, the cumulative coefffcient CCPF of pile side friction. The distributions of CCPF along the pile body of single pile and pile groups with different pile spacing were analyzed at different vibration times. This research has significant theoretical significance and certain innovation. And this manuscript is very well written. I think the manuscript can be accept in present form.

Reviewer 4 Report

 

The manuscript with title " Study on vertical load distribution of pile group-liquefied soil system under horizontal seismic environment" provides a good addition in literature". Following minor corrections are advised to authors.

 

1. Quality of the Figures is poor. The figures should be high resolution and high standard.

2. Page 3, Line59, the statements of “Qi Chunxiang [7] et al.” is recommended to corrected as “Qi Chunxiang et al. [7]”

3. Page 4, Line96, D-P model appears for the first time, it is recommended to write the full name.

4. Page 7, Line158, correct (See Figure 3. to (See Figure 3).

5. Page 16, Line290, -40~-60 is missing unit.

6. Page 16, Line305 and Page 20, Line361 correct 35S to 35s.

7. In this paper, the cumulative coefficient of pile side friction resistance CCPF is introduced. Is this formula established by the author or cited from literature? If it is your own, please explain the meaning of this formula. If not, please indicate the source of the cited formula.

8. Authors should check the manuscript for grammatical and language mistakes.

Round 2

Reviewer 1 Report

God job. This new version of the paper is way more adequate. Inclusion of validation chapter is interesting.  

Reviewer 3 Report

The authors have responded properly to my concerns. So I think this research could be accepted as its peresent form.
