Abstract

This paper discusses the soft clay soil stabilization with lime on the condition of the water content of the field. The sample used is soft clay of Marabahan, Barito Kuala, South Kalimantan. The water content of the sample is initially 76.2%. Samples were mixed with natural limestone that has been crushed and screened through a sieve No. 20 the percentage of 4, 8, 12, 16, and 20 percent based on the dry weight of the sample. Samples were mixed with lime cured for 7 and 14 days. Some of the tests performed in the laboratory include testing soil plasticity, direct shear tests, unconfined compression test, vane shear test, consolidation, and CBR. The results showed a decrease in the values of soil plasticity (liquid limit and plasticity index) and soil compression parameters (cc and cs) with the increased percentage of lime. While the values of cohesion, friction angle in, qu and qr, and CBR increases with increasing percentage of lime. The results also showed that the curing time effect on soil parameters were mixed lime.

Abstract

Height of oprit on  Sei Tuak Bridge reaches 3,5 m. Oprit made by  new system, modular wall. Advantages of modular system are : construcability, has a positive aspect of the schedule, the number of field workers and office project are few, aspect of quality dan productivity, testing. Modular walls is choosed  to increase aesthetics value. Modular wall are used on sand. However, in Sei Tuak Bridge modular wall built on clay. The purpose of analysis are analyzed stability oprit on the Sei Tuak Bridge. The result of analysis shows : soil active pressure at the first segment is 0.193 ton detained by deadmen is 0.235 ton, at the second segment is 0.2895 ton detained by deadmen is 1.873 ton, at the third segment is 0.2895 ton detained by deadmen is 2.474 ton, at the fourth segment is 0.355 ton detained by deadmen  is 3.075 ton, and the fifth segment is 0.732 ton detained by deadmen is 3.675 ton. Deadmen is located at a distance 3.5 m. Its longer than failure area at 2.103 m. Safety factor of  tierod at the first segment is 22.854, at the second segment 15.236, at the third 15.236, at the fourth segment is 12.425, and at the fifth segment is 6.026. Safety factor of bearing capacity is 1.122. And safety factor of this modular wall  stability is 2.724.

Abstract

The existence of the tower at Kuala Kapuas Kapuas Islamic Center Complex. The initial plan design of foundation. using precast reinforced concrete pile foundation with a square cross-section size of 50 cm x 50 cm with a depth of 22 meters. Another alternative is planned foundation due to change of plans superstructure. Preliminary design of foundations (piles and poerplat) subsequent to the rigors of land CPT data which is at a depth of 24 meters, calculation of the bearing capacity of the pile with a review of some of the methods in accordance with the data available land.From the analysis of the structure obtained by the forces transmitted to the stake, the maximum load bekerjauntuk one pole axial 59.6 tons and 1,527 tons for the lateral force. With concrete slab foundations diameter of 40 cm depth of 24 m configuration of 69 fruits and poer 1.3 m thick. Decrease pole group terjadi19,926 mm <smaller than would otherwise require a kind of high-rise buildings of 40 mm based on ASTM D1143-81 so that alternate designs tower foundation al-Mukarram mosque as a whole meets the technical requirements.

Abstract

The Martapura River Bridge is located on Jalan A. Yani KM 40 Martapura, Banjar Regency, South Kalimantan. Traffic processes that occur on Jalan A. Yani KM 40 Martapura often experience problems because congestion often occurs and the condition of the old IA bridge sometimes makes driving users feel restless when crossing the bridge located on the Martapura river. So that at the location of the Martapura river, it is deemed necessary to build a bridge next to the IA bridge so that the IB bridge to be built can be more sturdy and durable so that there is no anxiety for driving users and also to reduce congestion that occurs, where later the IB bridge will be used as a road with one way only towards Banjarmasin and the martapura IA bridge will be used as a one-way road towards the Hulu Sungai so that it will make it easier for traffic on Jalan A. Yani KM 40 Martapura. The methodology used in loading planning refers to SNI 1725-2016 concerning Loading Standards for Bridges. For the methodology in calculating the stress loss, refer to the NAASRA Bridge Design Specification on Chapter VI Bridge Design Specifications (Prestressed Concrete Design). For the methodology in calculating the moment of the vehicle floor using the Three Moment Equation method and for the method of subsidence of group pile foundations using the method of Schultze and Sheriff (1973), assuming that the pile group is the Equivalent Raft Foundation. The material used in the design of the upper structure is prestressed concrete, while the lower structure is planned to use reinforced concrete with a square pile. The results obtained are the T-Girder Prestressed type bridge with class A, 34 m span, 7 m traffic width, and 1 m wide sidewalk. Prestressed T-Girder is designed using fc' 40 MPa (K-482) Strands used are uncoated 7 wire super strands ASTM A-416 grade 270 with a diameter of 12.7 mm and an area of 100 mm2 with a tensile strength of 1860 MPa. As for the lower structure, the abutment uses concrete with a quality of fc' 25 MPa (K-300) with a height of 565 cm, a width of 480 cm and a length of 1050 cm.type piles Square Pile with a length of 15 m with a quality of 50 MPa (K-600) with a width of 60x60 cm with a configuration of 18 piles for each abutment. Estimated Budget Plan The cost of constructing the Martapura river bridge is IDR 8,129.511,475.00.-.
