Sensitivity Analysis of Anchored Slopes under Water Level Fluctuations: A Case Study of Cangjiang Bridge—Yingpan Slope in China
Round 1
Reviewer 1 Report
Dear Authors,
The work contains important considerations on maintaining the safety of slopes by using umbrella anchores. The work contains a few errors which do not detract from its substantive value. I also advise the authors to make a linguistic proofreading. In my opinion, after taking into account my suggestions and comments, the work is ready for publication.

Reviewer 2 Report
The article presents a sensitivity slope stability analysis of a reinforced slope through the classical limit equilibrium method. The manuscript could be written in a more formal and scientific way; besides English needs improvement. Although the paper concerns anchored slopes, nothing is said concerning this stabilization technique. Furthermore, some issues are found throughout the paper. Therefore, according to this Reviewer, a major revision would be necessary before the paper can be further considered for possible publication in Applied Sciences. All details are summed up in the following.
Required changes:
- Some language editing is needed, both from English and scientific point of view.
- Introduction is completely missing of any trace of explanation about slope stabilization techniques by means of anchors. In this context, a detailed explanation should be added. Furthermore, a comparison between this stabilization technique and other alternatives is required, such as for example drainage systems [1] and stabilizing piles [2]. For the sake of completeness, these suggested references are reported at the end of this report.
- Lines 32-35: this concept is very important and should be deepened. Some case studies could be mentioned, such as the following ones [3, 4].
- Equation 1 is not of general validity. Rather, it is valid only for cohesionless and dry slopes, characterized by a plane slip surface. This should be pointed out in the text.
- Equations 3/4/5: it is not clear the geometry that these equations refer to. A scheme should be added in the concerning section.
- Table 1: add the value of the friction angle. Besides, it is not clear what the coefficient ξ is, nor its physical meaning.
- Lines 237-243: it is not clear what the letter l, m, n
