Study for Longitudinal Deformation of Shield Tunnel in Side of Foundation Pit Based on Virtual Image Technique
Round 1
Reviewer 1 Report
<div><br class="Apple-interchange-newline">The work entitled Study for Longitudinal Deformation of Shield Tunnel in Side of Foundation Pit Based on Virtual Image Technique has the following deficiencies in its current state. Highlight the novelty of the study, since the Virtual Image Technique is used but not described. A further description of the Virtual Image Technique is missing. The quality of the images is quite poor. However, image 7 shows a great discrepancy between the measured and calculated results. Describe more broadly how measurements are made in the field. Add some photography if possible of the field measurement of the cases that are used as comparison/validation. Once all these observations have been corrected, resubmit your work since in its current state, I do not consider it adequate for publication.</div>

Reviewer 2 Report
Title: Study for Longitudinal Deformation of Shield Tunnel in Side of Foundation Pit Based on Virtual Image Technique.
In this study, a prediction model of enclosure structure deformation caused by the excavation of foundation pit is introduced using the virtual image technique.
As mention by the authors, in conclusions, several simplifications have been made in the analysis process. For example, the influence of tunnels, precipitation, layering of the foundation soil and the nonlinear effect of tunnels and soil is not considered. Therefore any scientific comments from the reviewer related to the study have no sense.

Reviewer 3 Report
1. I hate to put it as a major feedback, but all figures in the article are unreadable. They are all blurry and numbers are hard to recognize. Also, some notations are used inconsistently. For example, line 88 says "X" but where is "X" in Figure 1? Please proofread and rework them.
2. The authors claim to "select typical engineering examples", but all the cases studied are based in eastern China (mostly Shanghai). I don't think these cases are representative enough to reach a conclusion.
3. It's hard to understand the authors' contribution by reading the into. Please consider enumerating your contribution upfront as you did in the conclusion.

Round 2
Reviewer 2 Report
As a suggestion, the authors should give a brief overview of the structure of the paper at the end of the introduction.
