Tunnelling and Underground Space Technology incorporating Trenchless Technology Research

This supplementary material is associated with the paper "Simulation of the Behavior of Biologically-Inspired Swarm Robots for the Autonomous Inspection of Buried Pipes" by C.Parrott et al. It includes videos of the simulator used to generate the data used in this paper, the data itself, and the Matlab code for performing the analysis and creating Figures 5 - 8.

A new type of prestressing structure, the MUAA lining, is proposed in this research. In order to clarify the mutual action mechanism among the annular anchor, the concrete lining and the surround rock, a large-scale in-situ loading test and corresponding theoretical analysis are carried out.

This data is a test video for the injection of non-Newtonian grout in a regular water-saturated channel network. The test system consists of two parallel plates of plexiglass with the size of 1.2 × 1 × 0.015 m. The two sides along the length of the plates were sealed and the remaining two sides along the width of the plates were fixed by given water heads. One hundred and twenty rectangular plexiglass plates were homogeneously placed between the two plates to construct the regular channel network. The channel aperture is 1 mm and the width of the channels is 5mm. At the center of the top plate, a circular hole was drilled for injecting a non-Newtonian fluid. This test video contains the entire dataset of the propagation time and positions. More details can be found in [Håkansson U. 1987 Modellförsök – Icke-Newtonsk strömning i endimensionella kanaler.

The program of explicit procedure EAM in this paper titled "Incremental procedure method for the analysis of ground reaction due to excavation of a circular tunnel by considering the effect of overburden depth" is especially prepared for your examination.

In this article, one can find the output diagrams that include the distribution of vertical stress (v), radial stress (r), tangential stress () and radial displacement (ur) along the distance ratio (r/R), and the input data that contain Tunnel excavation radius, R (m); Depth of tunnel crown, h (m); In-situ stress ratio, Ko; Unit weight, g (MPa/m); Elastic modulus, E (MPa); Poisson's ratio, ; Internal friction angle,  (deg.); Dilation angle,  (deg.); Cohesion, c (MPa); Clockwise angle in polar coordinate , (deg.); and Confinement loss,  .

This spreadsheet implements the closed-form solutions for the computation of the racking coefficient, rocking coefficient, and racking-profile coefficient, to assess the seismic behavior of underground structures, as described in the companion paper.

This dataset includes raw data from a time-lapse ultrasonic tomography observation and a numerical simulation model. Four data sets are included in this article, and their format and naming conventions are explained in separate files. First, the ultrasonic tomography (UT) data at each 20 MPa intervals during the loading process. Second, the stress-strain data from the uniaxial compression test. Third, the combined finite-discrete element method (FDEM) model used in the manuscript. Last, the simulated AE data extracted from the simulation results.
