Abstract

Settlement problems can arise in construction of across in soft soil, especially the consolidation problems to need long time, whereas the concretion time to need short time relative. One way of overcoming these problems is the installation of Vertical Jute Fibre Drain in soft soil, it is the mean in order that to be able these drains speed up the consolidation process in the sub soft soil layers. The purpose of this method is to reduce the time required by the pore water to escape from the soil which also get to abbreviate for to reach the consolidation degree 90%, so that the damage of structure and maintenance cost can be reduced.

Abstract

The planned foundation at the hotel solis ubud resort and spa is a drill pole,caused soil conditions is impossible, to install shallow types. known from the results of soil tests obtained on the project, by using CPT method and SPT method. In this Thesis , the authors plan footing of the drill post by calculating capacity of the soil at that location with the planned depth using the data obtained from the building project, with two method, first standard penetrationt test (SPT) second cone penetration test (CPT) to compare cost efficiency of both methods in bore pile footing design, in hotel solis ubud resort and spa building project. the theoretical results obtained can be concluded that the SPT method used in the project, much more efficient in financing, than the results of the SPT method. on the calculation result get foundation size D = 45 cm for planning use method, whereas for planning using CPT method obtained size of foundation size D = 50 cm, with the same depth of 15m and the number of the same post that is 76 post.

Abstract

Many sites in Indonesia contain of soft soils which mainly located in farming areas, slopes, alluvials, low level areas. The main problem of soft soils for performing construction work is big settlement which is caused due to low ultimate bearing capacity of soils.These low bearing capacities occurred because of consolidation process proceeded in long time and slowly. To solve this problem the geotechnicians has tried to modify some methods to increase the ultimate bearing capacity of soft soils. There are many methods have been introduced and widely used for increasing bearing capacity. This paper discuss about four methods such as Bamboo Piles Method, Pre Loading Method, Vertical Sand Drainage Method, Geotextile Method.Bamboo Piles Method use bamboo as reinforced soft soils. Pre Loading Method used Pre Loading as the beginning loading. This loading aimed to conduct process of settlement in shortier time. Vertikal Sand Drainage Method required installation of vertical Drainage to clear sands on the soils layer. After draining and pre loading consolidation process was expected would be proceeding in shorter time. Geotextile Method used material of geotextile as tension force to reinforce soft soils so that the ultimate bearing capacity increased. The maximum bearing capacity would be obtained if users installed it as well as soil's layer condition.
