SAFETY IN TUNNELING AND EXCAVATION TUNNELING Tunneling work is widely carried out in the construction of railway, road projects and irrigation This work is specialized and hazardous because of cramped working space wet and slippery flooring, artificial lighting. Usually characterized by inadequate,
dam embankments. For example, some clays disperse when wet and result in tunnels forming in the embankment. Thus, the soil must be tested to determine its behaviour. To do the tests, samples of the soil must be obtained from the excavation area including the borrow pit which will provide much of the earth for the embankment (shown in Fig 6).
