6.The dependences of seepage velocity and bending strength on agglomerant content, forming pressure, particle diameter of the aggregate, soaking time, firing temperature and so on were discussed.
11.The shield tunnel at these positions is generally prone to fracturing and breakage, resulting in differential settlement, joint seepage, bolt fracture and segment cracking.
12.Fracturing directly into underground water hazardous underground seepage and leakage, and inadequate treatment and disposal of highly-toxic waste water can potentially contaminate drinking water around a fracking site.
13.Moreover, the metro shield tunnel of Line-9 in Shanghai was significant influenced by a 24-mlong dumped soil mound, leading to noticeable asymmetrical settlement and joint seepage.
14.Otherwise, the abrupt deformation will occur to shield tunnels, which will possibly further give rise to engineering accidents, for example, cracks of concrete segments, joint seepage, and distortion of track.
15.No water seepage exiting the downstream face of the embankment or eroding soil was evident in the time leading up to the breach, ruling this mechanism out as the main cause of failure.
16.And, we include drains that both relieve pressure so it can't build up within the soil and filter the seepage to prevent it from washing away soil particles from inside or below the structure.
