Among various practical measures used for restriction of the ground surface settlement in such tunnels driven in soft ground, selection of an appropriate excavation method plays a significant role. In this paper, employing suggested diagram by Yu & Chern, corresponding values of Niayesh tunnel has been inserted into the diagram. Later, two excavation methods namely: central diaphragm and side d...

The project of Hangzhou Metro Line 1 is the first metro line of the urban rapid rail transit system in Hangzhou, China, which is one of the largest municipal projects of Hangzhou and is being constructed commencing fromMarch 28, 2007 and expected to be completed by October 1, 2012. This metro line has a total length of 48 km and 34 stations, connecting Hangzhou downtown with the suburban area o...

Excavations in a soft soil area are usually associated with substantial difficulties. Taking special-shaped deep foundation pit Hangzhou clay as the research object, excavation performances, including groundwater level height, axial force, lateral wall, and deflection, ground surface settlement were monitored summarized based on data published literature similar excavations Hangzhou, P. R. Chin...

The increased risk to the safety of excavator personnel and difficulty in training them, combined with a manpower shortage, have led an demand for machine automation. This study applies long short-term memory algorithm automating bucket-tip trajectory planning AI system. Unlike other autonomous excavation techniques, proposed approach this performs bucket-trajectory without prior knowledge nonl...

Abstract Deep basement construction is characterised by a deformation challenge for the excavation pit and adjacent structures. Basement an unavoidable problem in urban areas. A case found Triumph Unit building block project, where 14 m will be constructed near existing Conducting site survey engineering analysis before deep essential to guarantee safety during construction. Site vital recommen...

Archaeological excavation documentation poses several challenges to spatial data management. This work gives a data model, respective query functionality and the description of the resulting prototype system for recording and analyzing the data produced during the course of an excavation. Based on a requirements analysis, we develop a data model that not only captures georeferenced finds (potte...
