Analisis Stabilitas Bendung Bajayu Di Tebing Tinggi, Kabupaten Serdang Bedagai Provinsi Sumatera Utara (Studi Kasus)

Abstract

Weir is a structure designed building durable. So the planning must be really well calculated, to avoid mistakes in the construction of the catastrophe that resulted in a more severe due to improper planning calculations and the maximum errors - errors that occur during the execution of development. In addition, losses that occur due to the planned construction of less than the maximum. Stability of the weir so it should be because the weir is a very important part that serves to raise the water level. The target to be achieved is the determination of the magnitude of the force due to its own weight, mud pressure, hydrostatic, uplift, active earth pressure and seismic forces that will be used as a reference to check the safety of the weir and slip roll style. Based on the results of the calculation of the target variable to be achieved over the safety factor at the normal time is 1.73 and style bolsters style slip safety factor is 2:54. Based on calculations it can be concluded that the weir is safe against style bolsters and slip with reference to the requirements for style bolsters Sfg> 1.5 and the requirements for style slip Sfge> 1.5.
