Theoretical and Experimental Studies of Engineering Structures on the Impact of Seismic Forces

Abstract

This article discusses theoretical and experimental solutions to this problem with a specific consideration of the transverse, relative to the axis of the pipes, seismic impact as the most dangerous for this structure. To ensure the reliability of these expensive structures, besides they are the most commonly used artificial structures, on which the possibility of further movement of transport after an earthquake depends, it is necessary to consider the longitudinal, relative to the axis of the pipes, the effects of seismic forces. An engineering analysis of existing drainage systems and pedestrian underpasses during earthquakes has been carried out, as a result of shifting the soil of the base of the pipes, the weak area is the joints between the links of pipes, bait trays, curbs, drainage drains and slope trays. The operability of highways in the southern region of Kyrgyzstan depends on the terrain and the features of the soil composition, the direction of the layers, since the fluctuations of the soil and engineering structures during earthquakes relate to complex mining and geological conditions. We have investigated the highway in the direction of Osh-Sary-Tash-Irkeshtam. Water pipes and underground pedestrian crossings are destroyed on sections of highways. On these sections of the Osh–Sary-Tash–Irkeshtam highway, salt-bearing anhydride rocks have been widely developed, which, as a result of groundwater circulation, leads to an increase in seismic activity in rocks. Under these conditions, the impact of seismic waves on underground and aboveground transport structures increases, which should be taken into account when designing artificial structures.
