Abstract

In the Pekanbaru-Dumai highway road construction in Section 5 will be built a bridge. The construction of the bridge is in the area of PT TGI gas pipeline. The construction of this bridge uses a pile foundation whose pile is carried out using a beating method using a hammer. The diameter ofthis pile is 60 cm with a hammer weight of 5 tons and a height of fail of 2.5 meters. This work method will produce vibrations that affect the condition ofthe gas pipe. One ofthe aspects that are affected by vibration is the deformation ofthe soil around the gas pipe. This soil deformation will affect the position ofthe gas pipe which, ifitforrns a fairly large slope, may cause gas pipelines to crack. The method used to determine the effect of vibration from the design ofthe gas pipeline is to use a vibration meter tool. vibration meter is a sensor device that is placed on the stake and on the ground above the gas pipe so that how much vibration and deformation of the soil can be seen. As a result from the test using vibration meter, it was found that the greater the wave velocity due to the design, the greater the deformation that occurs on the soil.
