Non-destructive Testing of Pile Foundation
Non-destructive testing (NDT) is a variety of techniques used to test objects without damaging or changing their properties. NDT is used in a variety of industries, such as oil and gas, engineering, and construction, and has been an integral part of the ......
radioactive prospecting
Introduction
Radiological exploration is a technique used to analyze and assess the composition of soils and bedrock underlying the surface. It is a non-destructive method that can be used to identify the hydrological, geological and geophysical characteristics of the subsurface. There are variou......
shallow reflection wave method
Introduction
The shallow refraction method is an important tool for the analysis of shallow subsurface structures. The method involves the analysis of seismic refraction data obtained from the subsurface in order to give an insight into the depth distribution of mechanical properties such as comp......
shallow refracted wave method
Introduction
Shallow refraction wave measurement is a geophysical method used to measure seismic velocity of subsurface layers. Originally developed in the 1920s, the method involves the use of a seismic source to generate a localized wave that is refracted when it reaches an interface between tw......
Remote Sensing Technology
Introduction
Remote sensing technology refers to the process of gathering information about an object or area from a distance. The data gathered can be used for many purposes, including mapping, monitoring, assessing, and managing the environment. This technology has become increasingly important......
