Abstract

Wharf structures operate in complex marine environments and are subjected to significant lateral loads from berthing forces, sea currents, and wave actions that affect structural behavior and foundation performance. One common method to improve lateral resistance is the use of inclined piles, which convert part of the horizontal load into axial compressive force. This study develops a numerical structural model of a wharf with variations in pile inclination from vertical to inclined configurations, limited to the modeling stage. Finite element modeling is carried out using SAP2000 based on wharf geometry, material properties of concrete and steel, soil parameters from site investigation data, and service load combinations representing operational conditions. All pile inclination models are analyzed using identical parameters to ensure consistent comparison. The evaluated responses include axial force, shear force, bending moment, and global lateral displacement of the wharf. The results show that the vertical pile configuration produces the largest lateral displacement of 0.147 m and high bending moments, indicating a flexible lateral response. As pile inclination increases, axial force rises from 6,471.024 kN and reaches a maximum of 6,496.89 kN at an intermediate inclination, while bending moments gradually decrease. Lateral displacement is reduced and reaches a minimum value of 0.133 m at the same inclination. Further increases in pile inclination lead to higher shear force and a gradual increase in lateral displacement despite lower bending moments. These results confirm that inclined piles improve the lateral performance of wharf foundations, with intermediate inclination providing the most balanced response between axial force, bending moment, and lateral displacement

Abstract

Drainage conditions in Palu City still need attention, especially in the drainage in Balaroa Village, drainage dimensions that do not match the required dimensions can cause flooding problems because the channel cannot accommodate the design flood discharge. One of them occurred in the Secondary Drainage in Balaroa Village, West Palu Subdistrict, the narrowing of the drainage channel along 200 meters resulted in disruption of the function of the drainage. The purpose of this writing is to determine the performance and the need for appropriate dimensions in the Secondary drainage Balaroa West Palu District. The research process begins with the collection of secondary data in the form of rainfall data, population data and also primary data obtained through direct measurements in the field. Then the abnormality test is carried out, analyzing the frequency of rainfall using the log person type III method, calculating discharge discharge, design flood discharge, evaluating drainage capacity and calculating channel dimension requirements. The results showed that the results of the evaluation of drainage performance along the 560 meters, at STA 0+000 to STA 0+200 were not able to accommodate the design discharge where the results of the design flood discharge with a 10-year return period of 14,935 m3/s were obtained, with the existing channel capacity at STA 0+000 of 3,390 m3/s, then the calculation of channel dimension requirements with an average channel discharge of 22,450 m3/s was carried out so that in the future a channel with a capacity corresponding to the design flood discharge could be built
