Finite Element Numerical Modeling And Parametric Study Of Geosynthetic Reinforced Pile-Supported Embankments, Abdallah Ikbarieh

LSU Master's Theses

This study directed at investigating the performance of the pile-supported embankment system utilizing a geosynthetic reinforced load transfer platform (GRLTP) using Finite Element numerical modeling. A 2D Finite Element Modeling (FEM) methodology was first developed using PLAXIS 2D 2021 computer software and verified by well-documented case studies in the literature of this system. Second, a performance prediction was made for a field case study of the Amite River Project near French Settlement, which is located along Route LA 16 Livingston Parish in Louisiana State. A comprehensive FEM parametric study was then carried out to evaluate the performance of the system …

Study On The Disturbance And Recompression Settlement Of Soft Soil Induced By Foundation Pit Excavation, Tai-Shan Lu, Song-Yu Liu, Guo-Jun Cai, Kai Wu, Wen-Jun Xia

Rock and Soil Mechanics

The deep excavation of foundation pit in soft soil layer will cause serious disturbance to the soil at the bottom of the pit. Affected by excavation disturbance, the mechanical properties and stress state of the soil at the bottom of the pit will change. Hence, it is important to accurately evaluate the degree of soil disturbance caused by excavation and the influence of disturbance on soil mechanical properties. Based on the summary of the existing evaluation methods of soil disturbance, taking the foundation pit excavation of Taihu tunnel as an example, the distribution of disturbance degree and the depth of …

ABSTRACT

Investigation of Foundation Failures

Ali Buabbas

Foundations form a very critical component of any structure. The integrity and lifespan of the structure are dependent on the strength and durability of the foundation. Under ideal conditions, immediately after the structure is constructed, the foundation meets all the requirements of the structure. However, after a while, due to the action of many other factors, the structure’s foundation may no longer satisfy the needs of the structure.

Some of the factors contributing to the failure of the foundation can be due to natural events. Construction engineers should anticipate these factors to minimize …
