| Summary: | This study area is located in the Jungkat in West Kalimantan. Based on the
geological map of Singkawang area and geotechnical engineering evaluation, this
area is mainly soft soil. This thesis aims to evaluate the engineering properties of
soft soil to develop the design of pile foundation and select the appropriate type of
pile to support the load of the machine generator. Furthermore, this study will
determine the settlement and critical buckling load of pile, which has been
selected.
The analysis of this research has evaluated on geological and geotechnical
conditions of the study area to understand about characteristic of soft soil
foundation by finding the influence to engineering properties of soil to select the
appropriate type of pile foundation. Moreover, the design of pile foundation has
been done into two sections (circle and square section). For settlement analysis
was performed by manual and model analysis (Plaxis analysis). In addition, the
critical buckling load was calculated by using Euler and Davisson method based
on the comparison of each end condition boundary of pile.
As the results from geological and geotechnical evaluation, this area is
covered by only one rock unit formation, which consists of mud, sand, gravel,
locally calcareous and plant material. In addition, there are two main layers. The
first layer is Silty Clay layer, and the second layer is Sand. The depth of this first
layer is start from ground surface to 41 m. It has shown the most important factors
that cause the influence to engineering properties that can affect to the pile
foundations such as: low bearing capacity, excessive water content, high
compressibility and long term settlement. The second layer is consisted of two
types of soil (fine sand and medium sand), is a hard layer. The Pre-Stress
Concrete pile was selected to design the ultimate bearing capacity, settlement, and
critical buckling load in two sections (Circle and Square section). It has the total
44 m for length |
