Round 1
Reviewer 1 Report
1 check the format of the references in the manuscript
2. move L53-54 to the final paragraph of the Introduction
3 Fig. 2, denote the name of test components instead of numbers
4. Fig 3, Chinese characters are found in the figure
5 change the description of soil to sand
6 Fig 4, give photos of the specimen
7 L132 describes the basic properties of geogrid
8 section 2.3, discuss the tensile and pull-out tests one by one and give their test diagram
9 L178-180, no clear what is the arch effect. Better discuss the test result only.
10. L187, not clear how to calculate.
11. L211 can not find what is “interlocking”, better discuss the observations only
12 L246 change tensile rate to loading rate
13， Table 4 is repeated by Fig. 9b
14, Eq 3 it is not clear how to calculate
15. Eq 5 confirm it is phai or phai’
16 Fig 11, Chinese characters are shown in the figure.
17 Appendix, name the figure and equations separately

Reviewer 2 Report
Major issues:
The authors should show some pictures of the tester and/or test setup.
Figures from 6 to 9 are incorrect when determine the values of the tensile strain (%) of the test curves, because the original length of the geogrid cannot be used. The geogrid length to determine the strain (%) is not the same as the original length when applying the confinement pressures (vertical pressures).
For that reason, the data from tensile tests cannot be used to evaluate geogrid properties including the secant tensile stiffness.
Conclusions (a) and (b) cannot be drawn from the test in this study and the test curves cannot be used because the tensile strain (%) determined in this study is incorrect. The manuscript should be prepared with better quality and more useful to readers.
However, Figure 10 for pull-out tests can be used to estimate interaction properties between soil and reinforcement.
Other issues:
There are a lot of typo mistakes and Chinese words in this manuscript.
Figure 2 should be nicer.
It is reasonable to remove word “represents” in the note of Figure 2.
Figure 3 - particle size distribution curve – should add inner vertical lines to show the log scale and remove Chinese words.
Table 1 should follow the journal guideline to show the units: (%), (mm), ..
Line 114: “drawing rate” should be “pull-out rate”
Line 133: letter “s” - typo mistake.
Line 151: Check the unit (%) in “ (20% ± 1%) mm/min “
Line 152: “drawing test” should be “pull-out test”
Line 175: Table 2 “Table of testing program” should be “Testing Program”
Explain why using the big change of the pull-out rate from 1 mm/min to 150, 200 and 247.
Line 193: For the tensile test, authors should show test pictures or some drawings of the tests.
Figure 11. Replace Chinese words
Please revise the text throughout the manuscript.
