Abstract

Soil is a material that has a significant influence on the performance of building construction. Soil improvement techniques are soil stabilization measures by improving the characteristics of the original soil, to meet the technical requirements required by the construction, such as increasing the bearing capacity and shear strength of the soil, reducing soil compressibility, increasing or decreasing soil permeability, and so on. In the Tuban Ring Road Development Project, there are soft clay soils at STA 9+050 – 9+075, where the subsidence was seen after placing selected embankments 30 cm thick. The analysis used in this study uses the geotextile method as an alternative to reinforcement at STA 9+050 – 9+075 in the Tuban Ring Road Development project. From the data obtained it is known that the soil appears to be soft soil. The type of geotextile used is UW-250 with a strength capacity of 5.20 t/m which serves as a separator for the reinforcement of the Tuban Ring Road Development Project at STA 9+050 – 9+075. Based on the data analysis performed, it can be concluded that the amount of settlement that occurs due to loads on soft soil at STA 9+050 – 9+075 is 57.35 cm and the consolidation time obtained is 190.311 years. The length of the geotextile (L) planted at STA 9+050 – 9+075 in the Tuban Ring Road Development project is 9.884 m installed in 1 layer. The value of Safety Factor (SF) on soil with selected embankments and geotextile reinforcement at STA 9+050 – 9+075 is 2.7, so it is known that the use of geotextile as an alternative to soft soil improvement at STA 9+050 – 9+075 in development projects Tuban Ring Road.

Abstract

The construction of the Tuban Ring Road Project or the so-called Ring Road/Tuban Ring Road is included in the Semanding District, located in Tuban Regency. This area is a potential road access because the road is the main access connecting the city of Tuban and the city of Lamongan. In field conditions at STA 9+050 to STA 9+075, there is land subsidence due to the additional load on the original soil. A soil improvement is needed to overcome the problem of subsidence in these conditions. Based on the conditions described, the Prefabricated Vertical Drain (PVD) method can be used as an alternative to soil improvement on the Tuban Ring Road. So the embankment height is 1.50 m. The length of time for land subsidence without using PVD is 197.311 years. Then after using PVD, the distance and depth of PVD installation is obtained, namely a triangular pattern with an installation distance of 1 m, it takes 12.5 weeks.

Abstract

The wharf is one of the supporting facilities for the process of loading and unloading goods on ships. For services for long-term ships and loads caused by the process of loading and unloading ships, the safety of the wharf needs to be improved by strengthening the foundation. Berlian Pier uses a steel pile foundation with a diameter of 1.016 m and a length of 32 m. This study used the Meyerhoff method to calculate the bearing capacity of the piles and N-SPT data for the Reinforcement of Wharf Structures Using Diameter Variations at Berlian Surabaya Pier. Based on the re-planning that has been done, it is concluded that a diameter of 1.00 m and a length of 32 m obtains a single pile bearing capacity of 8164 Tons, shear resistance of 28120.4 Tons, axial bearing capacity of 8345.42 Tons. Immediate settlement of 38.551 mm, annual settlement of 00,0201 mm, long-term settlement of 0,193 mm, and total settlement of 48,050 mm. Keywords: Variation Diameter, Carrying Capacity, Settlement

Abstract

Soil acts as a building material in various types of civil engineering work, on the other hand land plays a role as a support for building foundations such as embankments, highways and railroads. Soil improvement is a type of soil stability that is useful as soil improvement and performance required by technical requirements. In an effort to increase the carrying capacity of the soil, several methods can be used, such as: soil improvement using Replecement Soil, PVD Method, Preloading, Micropile, Geotextiles, etc. In this study, the geotextile method was used as an alternative reinforcement to find a larger and better safety number (SF) for soil conditions adjacent to (Groundwater Table), and can be the most effective alternative soil improvement method. Based on the analysis of the data, it was concluded that the total load (q) is 31 layers of non-woven which is 2 layers, with a length of geotextile (L) of 1.825 m. The safety factor geotextile method non-woven = 2.4.
