Modeling Microtunnelling Construction Operations with WebCYCLONE

Microtunnelling operations do not reach the highest possible productivity due to influences by different soil compositions.Hence, there is a need for a better understanding of the construction process and of those factors influencing productivity. Theefficiency ofMTBM （microtunnel boring machine） will be increased by that knowledge. In the paper, a flexible simulation module isdeveloped. It helps to analyze the processes and to identify the influence of different soil compositions on the productivity ofmicrotunnelling operations. In view of these objectives, a model describing the microtunnelling process for an actual project at thecity of Recklinghausen, Germany is created by using CYCLONE methodology. Subsequently, the WebCYCLONE is applied toexecute the CYCLONE model in order to get the results. It helps to analyze and identify the influence of different soil compositionson the productivity of tunnel construction with microtunnelling in the job-site.
