Analisa Perhitungan Dimensi Turap Kayu (Panjang Kayu Ditanam Dan Tebal) Sebagai Dinding Penahan Tanah Sementara

Abstract

At this time, the development of retaining structures continues to be optimized according to the available land use, to deal with current and future landslides. The structure of the retaining wall (Turap) is expected to provide a solution for the handling. Based on the type of material used, several types of sheet pile are known, namely; wood sheet pile, concrete sheet pile and steel sheet pile, and based on the type of construction there are two types, namely; cantilever type and anchor type. Sheet pile made of wood, the function of this material is to retain the soil which is not so high. This is because the wood material will not be able to withstand excessive soil or gravel loads. In a handling, knowing the function or planning for handling avalanches is very important, because by knowing the purpose and function of the plan, it can be easier in the design and planning process. Calculations for the quality and efficiency of handling can be achieved as desired. The purpose of this study was to analyze the planning calculation of the dimensions of the temporary wood sheet pile (length of planted wood and thickness) as a soil barrier that was built to prevent landslides caused by the intensity of rain. From the results of the research that has been carried out, the planning of wooden sheet piles with a width of 1 meter and 2 meters as retaining walls and for soil volume ranges from 20 KN/M3-30 KN/M3 while the height of sheet piles is 1 meter - 4 meters. It was found that the length of the sheet pile planted did not affect changes in the volume of the soil while the thickness of the wood did.
