Rectification of Gas Pipeline Bridging with the Support of Experimental Stress Analysis and Means of Regression and Correlation Analysis
Round 1
Reviewer 1 Report
This paper discussed the potential risk of serious damage to the existing pipeline systems, caused by implementation of landscaping for the new pipeline systems. Experimental strain gauge measurements and related statistical procedures, including regression and correlation analysis, were also considered.
However, the novelty of this paper is still unclear. This paper described the research background but the state of the art of the related research was presented inadequately, so that the motivation and potential novelty of this paper were hardly obtained. Moreover, this paper discussed some regression models and correlation analyses, but the experimental details and validations were not effectively organized. In conclusion, the topic of this paper is interesting, but the quality of this paper should be further improved.

Reviewer 2 Report
An interesting topic, especially at this time, marked by complications with energy supplies. Genereally, I would suggest a deeper explanation of statistical methods used. Despite that, the current version of the contribution is, according to my oppinion, fully acceptable for publishing.
Two more suggestions/questions to authors: 1) The object for the analysis the double-arch self-supporting pipe was chosen. Could you comment/estimate how the results would be in case of different type of briding through the water stream ? 2) Line 145: it is stated that the aim is to determine the change of stresses at the outlet side of the pipeline. In the following line (146) you describe that the strain gauges are mounted at the place of pipe INLET. This statement is quite confusing for me.

Round 2
Reviewer 1 Report
This paper deals with the connection of the issue of rectification of the structural system, the corresponding experimental and related statistical analysis of stresses. The solution was demonstrated on the example of replacing the above-ground gas pipeline with an underground solution. The topic of this paper in interesting and has potential engineering value. The quality of this paper has been effectively improved. The questions in last review round has been well solved, and the novelty of this paper is more clearly presented.

The requested changes have been done correctly except for the following one:
Please update the number of the headline accordingly:
Line 338 should be changed to 2.2.3, not 2.2.2.
2.2.2. Regression analysis of experimentally obtained results line 265
2.2.2. Correlation analysis and regression dependencies testing Line 338
