Application of wave equation theory to improve dynamic cone penetration test for shallow soil characterisation

Journal of Rock Mechanics and Geotechnical Engineering, 2022
Among the geotechnical in situ tests, the dynamic penetration test (DPT) is commonly used around the world. However, DPT remains a rough technique and provides only one failure parameter: blow count or cone resistance.

Application of Dynamic Cone Penetration Test to Gypseous Soils

Tikrit Journal of Engineering Sciences, 2018
Dynamic cone penetration test (DCPT) is a fast, economical and easy to conduct. It is widely used to assess the strength of natural and compacted soils. The device is introduced in the 1950s. However, it was newly introduced in Iraq.

The performance comparison of the decision tree models on the prediction of seismic gravelly soil liquefaction potential based on dynamic penetration test

Frontiers in Earth Science, 2023
Seismic liquefaction has been reported in sandy soils as well as gravelly soils. Despite sandy soils, a comprehensive case history record is still lacking for developing empirical, semi-empirical, and soft computing models to predict this phenomenon in ...

A Novel Method for Testing the Effect of Base Post-Grouting of Super-Long Piles

Applied Sciences, 2022
The base post-grouting technology is widely used in pile foundation engineering to improve its behavior. For super-long piles, due to the large compression of pile shaft, conventional static load tests cannot effectively test the effect of post-grouting ...
