Abstract

Pile bearing capacity is the ability of the pile to support the load acting on the pile. The bearing capacity of the pile foundation must be greater than the load that occurs so that it can safely hold the building. Likewise for the pile foundation used in the construction of the Catholic Center Building, which must be able to support the loads that work on it. For this reason, it is necessary to calculate the bearing capacity of single or group pile foundations to support the load of the Catholic Center Building. Many methods are used to calculate the bearing capacity of piles, one of which is by using the equation proposed by Meyerhof (1976) which uses data from the Standard Penetration Test (SPT) obtained. In this method the value of N from the SPT results is used to find the pile end resistance and pile friction resistance. From the results of the calculations, the total weight of the Catholic Center (P) building is 20462 KN. The single pile bearing capacity based on the first point is 320.2 KN and the second point is 550.7 KN. The total bearing capacity of the pile group contained in the Catholic Center Building Construction based on drilling point one is 17261 KN and drilling point two is 30179 KN. 24255 KN. Thus the pile foundation in the construction of the Catholic center building is able to safely support the weight of the building, namely Qa = 24255 KN > P = 20462 KN.

Abstract

Retaining walls serve the purpose of withstanding lateral pressure from the soil behind them. This construction can be considered as an alternative for addressing potential landslides along the embankment of Hutumuri village road. The aim of this research is to plan a retaining wall as one of the reinforcement alternatives for the embankment along the section of Hutumuri road from Station (STA) 1+200 to 1+270. The planning of the retaining wall along this road section begins with a soil stability analysis using the simple slice method. Subsequently, employing the Terzaghi method, the stability of the wall against soil pressure behind it is analyzed to prevent displacement and potential collapse during the construction of the retaining wall. Utilizing the Simple Slice method and Rankine's theory to assess the slope conditions and the construction of the retaining wall along Hutumuri road section, values for the slope safety factor are obtained. In the unsafe condition, the slope safety factor is less than 1.2, indicating the need for an alternative slope reinforcement, such as a retaining wall. The analysis results for the stability of the Counterfort-type retaining wall indicate that it does not meet the requirements. This is due to the fact that, in section I, the soil bearing capacity safety factor (FS) is 2.454, where the value of FS is less than the recommended value of 3, signaling the need for further consideration and potential adjustments in the design.
