Soil Mech Prob_lets Solve it!!!
Let's solve this Civil CEans!!!😀
In times of high water in the rivers in The Netherlands, when the water table rises practically to the crest of the dikes, local authorities
sometimes put sand bags on top of the dike. Is that useful?
Another measure to prevent failure of a dike during high floods, is to place large sheets of plastic on the slope of the dike. On which side?
Will the horizontal stress in the soil mass near a deep river be relatively large or small?
The soil at the bottom of the North Sea is often much stiffer in the Northern parts (near Norway) than it is in the Southern parts (near
London). What can be the cause?
A possible explanation of the leaning of the Pisa tower is that the subsoil contains a compressible
clay layer of variable thickness. On what side of the tower would that clay layer be thickest?
Another explanation for the leaning of the Pisa tower is that in earlier ages (before the start of the
building of the tower, in 1400) a heavy structure stood near that location. On which side of the tower would that
building have been?
In many cities of the world leaning towers may be found, though nowhere so spectacular as in Pisa.
An example is shown in Figure of the tower of the Old Church of Delft, along the canal Oude Delft. Can you
imagine what is the probable cause in this case, and can you suggest a simple technical solution to prevent further leaning?
