Selection Of

The collapsible loess ground treatment methods include dynamic compaction, soil replacement cushion method, lime-soil compaction pile composite foundation, pile foundation, etc. Each method has its advantages and disadvantages. The bearing capacity of collapsible loess is not lower, it is non-soft soil. The purpose of the collapsible loess ground treatment is to eliminate the collapsible at the most, few to increase the capacity and improve the heterogeneity of the foundation. In this paper, the collapsible loess foundation treatment methods are been compacted from the technical and economic factors. And the key issues of the collapsible loess ground treatment methods are discussed.

Having in mind uncertainties linked with the nature of rock masses, it is a challenge for geotechnical engineers to characterize them in a credible manner, especially if the rock mass in question is a notoriously complex karst with its distinctive features such as voids and discontinuities. A large range of geophysical methods are useful tools in the characterization efforts and their utilization in karst environments nowadays is a non-negotiable requirement, even though near-surface scattering significantly affects the acquired data. This paper demonstrates the versatile applications of seismic geophysical methods for geotechnical engineering in karst, from mapping of near-surface karstic features to the application of elastic wave velocities in determination of small to large strain stiffness of karst. The highlighted practical examples offer a step forward from the traditional interpretation of seismic surveys, making them a prosperous tool in geotechnical engineering investigation works, design and quality control campaign.
