PERENCANAAN BANGUNAN PENGAMAN PANTAI TIPE TURAP PADA PANTAI TINOMBO ULATAN

Parigi Moutong District specially Subdistrict Palasa village of Ulatan is a coastal region with huge potential both from the sea and aquaculture. Lately, the coastline in the region has experienced abrasion / eroded by the waves. Alternative planning using steel sheet pile construction, planning is based on original land data, land heaps. and tides. The sheet pile height is planned 3.12 m based on the planned water level elevation The steel sheet pile construction is analyzed based on three conditions namely tide, normal and low tide. The results of steel sheet pile construction planning with the three conditions of the water level found that during the tide level the actual D piling depth = 2,265 m, with PSA-31 pile type, under normal water conditions the actual D piling depth value = 2,694 m, with PSA-31 pile type, and at low tide conditions obtained the actual piling depth D = 3,420 m, with PSA-31 pile type. The calculation results obtained value of the planned piling depth that is at low tide, this is due to these conditions is the most critical condition so that the lateral earth pressure that occurs is greater.
