Abstract

The Research Area is in the Duri Region, on the Pekanbaru-dumai toll road section section with coordinates 101 ° 15'50.18 "-101 ° 15'56.01" East and 1 ° 13'51.49 "-1 ° 13'42.30" NU. This research was carried out because of the piling process on the road that caused vibration to the PT.TG gas pipeline. The purpose of this thesis is to find out how the effects of vibration due to staking in the gas pipeline. The method used in this study is the geoelectric, magnetic, sondir and drill methods, the magnetic value of the study area ranges from ± 52151.23 to ± 36344.87. The geoelectric value in the study area has the highest value of 3990 Ωm and the lowest 0.223 found in the trajectory 3. On drill 1 with a depth of 20 m there are 4 layers, namely pile (0-0.5m), red clay (0.5-2.5m), bright gray clay (2.5-4.5m) and greenish gray claystone (4.5-30m) and drill 2 has 5 layers, namely landfill in the form of sandy clay (0-0.5m), yellow sandy clay (0.5-2.30), greenish-gray clay (2.30-5m), clay-gray clay (5-23m) and claystone dark gray (23-30m) with a conus value reaching 100kg / cm2 at a depth of 21 m. The highest wave velocity value at 2 times the test is 18,930 mm / s which is still below the standard limit of PT. TGI, while the value for the amplitude has a value 0.4726 mm and exceeded the standard limit, but the results of the calculation of te the right pipe received with a value of 63808.91 Psi is still below the safe limit which is then based on the same data modeled using 2D plaids and get the results of pressure far below the safe limit of 0.031 MPa
