The forecast of an emergency condition of a site of a ring motorway around of St. Petersburg

     It is known, that exist on the Earth of a place where piles do not hold loading, and dip into a ground. In such zones the length of piles can be increased, but it will give nothing. As it was established with the help of the SSP method, these zones are directly above tectonic disturbances.
     As a result of realization SSP profile along a line of a ring motorway around of Saint Petersburg the places was found out where the constructions of a piles is not must. One of these zones has fallen to a place of erection of an outcome with the Vyborg highway.

     The funnel-shaped object on the SSP-section is shown by a dotted line.
     The installation of a pile construction in this zone was connected to the big complexities. Does not cause doubts, that exploitation of this place of a road will be accompanied by its constant repair.
     This ring motorway in some places drives lengthways already laid highway. At realization of the SSP method along such sites it showed that the condition of an asphalt covering on old highway unequivocally depends on presence of tectonic disturbances. In zones of tectonic disturbances of asphaltes is broken, and outside of these zones the cover of a road is in good condition.
