1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

During tunnel construction by the drilling and blasting method, the blasting stress waves may affect the mechanical response of existing tunnel lining structure. Based on the similarity theory, a mechanical response of existing tunnel lining structure by blasting model test is designed. The similar material of surrounding rock, explosives, and tunnel lining structure are determined by the similarity of physical mechanical parameters. This study investigates the mechanical response of existing tunnel lining concrete and reinforcing steel‌ by the action of adjacent tunnel blasting. The experimental results reveal the maximum strain distribution and stress peak value of existing tunnel lining concrete and reinforcing steel‌ affected by blasting load. Meanwhile, the equations are established between the peak particle velocity (PPV) and the strain (or stress) in tunnel lining concrete and reinforcing steel‌ affected by adjacent tunnel blasting as well. These Eqs. (13) and (14) can be used to predict the maximum stress value of existing tunnel lining concrete and reinforcing steel‌ by the action of blasting load. Simultaneously, these equations have been validated and adjusted by an actual engineering project field test. Thus, evaluating the stress states of tunnel lining caused by adjacent tunnel blasting is more effective. This finding is of great significance for evaluating the stress state of existing tunnel lining structure, as well as providing theoretical guidance and reference for the design of blasting parameters on adjacent tunnel construction.
