Co-Relation of SPT And PLT for Estimation of Settlement for Khyber Pakhtunkhwa Soils

Abstract

To create secure and effective foundation systems for civil engineering projects, the assessment of soil settlement characteristics is essential. The purpose of this study is to establish a correlation between the Unconfined Compressive Strength (UCS), Standard Penetration Test (SPT), and Plate Load Test (PLT) to evaluate the settling behavior of soils in the Khyber Pakhtunkhwa area.

As part of the research approach, undisturbed soil samples were gathered from different parts of Khyber Pakhtunkhwa. Laboratory experiments were used to establish the physical and geotechnical parameters of the soils. PLT and SPT tests were conducted at representative locations by field investigations, and soil samples were extracted for laboratory testing using geotechnical borehole drilling.

To determine links between PLT and SPT, data from field and laboratory research were subjected to statistical analysis and correlation tests. Based on the PLT and SPT data, multiple regression analyses were carried out to create predictive models for assessing the settlement behavior of Khyber Pakhtunkhwa soils.

The findings showed that the PLT and SPT parameters showed strong relationships, demonstrating their dependency for assessing the soils of Khyber Pakhtunkhwa's settlement characteristics. With readily observable parameters, the correlation models that have been created offer a useful tool for assessing the settling behavior of these soils.

The results of this study will be useful to designers, construction managers, and geotechnical engineers in Khyber Pakhtunkhwa who plan and implement foundation systems. The correlations that have been created will augment comprehension of soil behavior, elevate the precision of geotechnical assessments, and aid in the creation of effective and economical foundation designs.
