Abstract
Terdapat kondisi crossing pipa gas KP-14+000 di yang berada pada down stream kelokan sungai posisi serong, sisi kanan berada pada tebing luar kelokan sehingga terancam gerusan akibat arus kuat pada sisi luar kelokan tersebut. Telah diantisipasi masalah tersebut dengan check dam agar memperkecil resiko gerusan yang dialami pada pipa tersebut. Untuk itu diperlukan evaluasi kinerja check dam sebagai perlindungan crossing pipa tersebut dengan analisa hidrologi, analisa sedimentasi, analisa stabilitas dan analisa tata letak check dam.
Pada analisa hidrologi direncanakan debit banjir periode ulang 25 tahun dengan debit maksimum 2.397,41 m3/s, besar angkutan sedimen total sebesar 1.441,160 m3 per bulan dan perbedaan elevasi tertinggi setelah terjadi sedimen sebesar 0,0003 m dan analisa stabilitas guna mengetahui gaya geser, gaya guling dan daya dukung fondasi terhadap keamanan bangunan serta perbandingan tata letak bangunan perlindungan pipa antara kondisi eksisting dan kondisi setelah dirubah tata letaknya.
=======================================================================================================================================
There is a condition of crossing the KP-14+000 gas pipeline in the down stream of the serong position of the river bend, the right side is on the outer edge of the bend so it is threatened by scour due to the strong current on the outside of the bend. The problem has been anticipated by check dam to minimize the risk of scour experienced on the pipe. For this reason a check dam performance evaluation is needed as a protection for crossing the pipeline with hydrological analysis, sedimentation analysis, stability analysis and check dam layout analysis. In the hydrological analysis it is planned that the 25-year return period flood discharge with a maximum discharge of 2.397,41 m3 / s, the total sediment transport is 1.441,160 m3 per month and the highest difference in elevation after sediment is 0,0003 m and stability analysis to determine the shear force, rolling style and carrying capacity of the foundation for building security as well as a comparison of the layout of the building to protect the pipeline between the existing conditions and conditions after the layout has been changed.
