Abstract

Indonesia is a disaster-prone area to landslides and Indonesia has widely spread of clay soils, so that continuous the study of clay is necessary about characteristics of clay soil. The purpose of this study is to determine the empirical relationship plasticity values, fractions and mineral soil and to predict the effective shear strength c’ and f’. Analysis is about linier regression to infer the relationship between effective shear strength c’ and f’ with plasticity values, fractions and mineral soils, then analyze slope stability on Tol Jatingaleh – Krapyak. The results showed that LL and PI are more large then c’ value is more large too, but it is reverse about PL. If PL is more large then c’ is more sligthly If value of c soils is more large then c’ is more large too, on the contrary if it is f’ soils. Soils with a large content of montmorillonite tend to have great cohession. Decreasing of montmorilonite, it means that value of c’ is more slightly because rise of illite and kaolinite. Further research is indispensible to get enough data to do non-linier regression and multivariate regression to produce a reliable value R > 0,9.

Abstract

Sebelimbingan – Martadipura road has a length of 2.8 km, it was built in the sub-district of Kota Bangun, Kutai Kartanegara Regency, East Kalimantan. Trace of the road must pass through areas with very soft soil condition. During the rainy season, the location of  alignment in this road flooded. To overcome these problems then built bridge using Slab on Pile structure. Slab on Pile structure consisting of slab, pile head and pile foundation. Loading standart on the structure refers to the SNI T-02-2005 (Standar Pembebanan Untuk Jembatan). Modeling of pile foundation used elastic spring reaction model, which can represent the bearing capacity of pile foundation.

Abstract

Suru bridge is located in the village of Suru, Bantar bolang, Pemalang linking local and regional Кesesi Bantar Bolang route its span 144 meters above the river suru. Suru bridge replacement is based on conditions that exceed the design life of the bridge, steel truss bridge already rusty and the effective width of the bridge that does not meet the standards to serve the transportation needs. On the condition of the bridge was originally designed using the bridge structure type steel frame, then in this final project design for the replacement bridge suru use this type of prestressed concrete structures. At this early stage analysis exsisting conditions, the structural design of the upper structure and sub structure as well as the calculation of the Budget Plan (RAB). Planning the structure take into account the burden that might occur that burden alone, additional dead load, traffic load, wind load and earthquake loads. In planning prosess carried out calculations using LRFD (Load and Resistance Factor Design) is then performed under the structural design with the initial steps do dimensioning abutments, pillars and foundation .For foundation wells are used caisson.
