Foundation Design and Geotechnical Engineering
• In engineering, a foundation is the element of a structure which connects it to the ground, transferring loads from the structure to the ground. … Foundation engineering is the application of soil mechanics and rock mechanics (geotechnical engineering) in the design of foundation elements of structures.
Our earthquake and geotechnical expert shall consider several options of foundation system, compare cost of each option and select the most economical foundation system.
• Classification of foundation design:
A. Shallow Foundation
i. Wall Footing
ii. Isolated column/Column Footing
iii. Combined Footing
iv. Cantilever (Strap) Footing
v. Mat (Raft) Foundation
B. Deep Foundation
i. Pile Foundation
ii. Pier Foundation
iii. Well (Caissons) Foundation
ii. Site amplification essential for seismic zonation is defined here as a peak value of spectrum ratio between ground surface and a base layer. ... The value of Vs was evaluated from fundamental mode frequency and a thickness of equivalent surface layer in which peak amplification was exerted.
