The effect of the construction of the 4th subway line of Budapest (Metro4) on the potential surfaces of the gravity field has been investigated from the aspects of monitoring vertical deformation. In the study mass loss due to the excavation of the two tunnels and of the stations has been considered. Practically, the effect of the mass loss on leveling measurements was determined at a level 1m above the ground, roughly simulating common instrument heights. The indirect effect of the actual… CONTINUE READING
