Abstract

Pembangunan flyover dari dan menuju terminal teluk lamong melewati berbagai fasilitas dan infrastruktur yang sudah ada (existing building), salah satu infrastruktur yang di lewati oleh flyover adalah pipa gas tertanam. Perlu adanya analisis mengenai dampak pekerjaan pembangunan pada integritas pipa. Beberapa pembahasan yang akan dilakukan meliputi tinjauan getaran yang dihasilkan oleh penanaman pondasi serta tinjauan tekanan yang diakibatkan beban vertikal akibat jatuhnya material konstruksi dan kendaraan berat yang melintas pada lokasi tanam pipa. Dari analisis didapat hasil tekanan pada pipa akibat beban kendaraan sebesar 7.72, 5.22, 0.48 kN/m2 untuk kendaraan dengan berat 10, 5, dan 0.5 ton, sedangkan untuk beban tumbukan dihasilkan tekanan sebesar 3.97, 8.65, 12.15 kN/m2 dan kedalaman penetrasi 2.9003E-05, 0.000144732, 0.000288759 m untuk tumbukan dengan ketinggian jatuh 1, 5, dan 10 meter. Untuk getaran akibat pemancangan pondasi dari jarak 5m mengakibatkan getaran 18.81625, 21.45382, dan 21.95229 mm/s menurut tiga variasi ketinggian hammer pile. Dari semua tinjauan analisis tidak ada parameter tinjauan yang melewati nilai parameter yang diatur dalam Codes and Standard sehingga dapat disimpulkan bahwa pekerjaan pembangunan tidak mengurangi integritas pipa. ===================================================================================== Teluk Lamong flyover road is going to be build on top of numerous existing public facility, one of the most critical facility below the flyover road is a gas pipeline buried just 1 meter underground. It is very crucial to conduct an analysis reviewing the effect of soil effect due to construction work to gas pipeline integrity. The analysis consists of reviewing the effect of vertical weight due to heavy duty vehicle, falling construction material, and effect of pile driving ground induced vibration. The analysis carries out the result of pressure on the pipe due to heavy duty vehicle to be 7.72, 5.22, 0.48 kN/m2 due to 10, 5, and 0.5 ton of vehicle respectively, and due to falling construction material resulting 3.97, 8.65, 12.15 kN/m2 pressure on pipe and 2.9003E-05, 0.000144732, 0.000288759 m soil penetratioin for 1, 5, and, 10 m construction material falling height. The ground vibration due to pile driving done 5m from the pipe analysis resulting in 18.81625, 21.45382, and 21.95229 mm/s with three different height of hammer pile drop. According to the analysis given, none of the result exceed value given in respective codes and standard, as for the construction work will give no threat to pipe integrity.
