Various Standard Codes on Pile Foundations in Different Countries
Pile foundation is a long or slender column that is constructed from materials like reinforced concrete or steel. It is a type of deep foundation which is used to support the structure and transfer the load at desired depth either ...
What is Transported Soil?
Transported soil is weathered soil deposits that are transported from one place to another by natural agents like wind, water, and glaciers. Based on the means of transportation, there are wind-transported soils, water-deposited soil and glacier-deposited soils. A brief description ...
What is Rock Reinforcement?
Rock reinforcements are additional supports provided to the rock structures to improve its stability and load carrying capacity. Rock reinforcement utilizes the inherent property of the rock structures to behave like a self-supporting single unit. Rock reinforcements can be provided ...
4 Different Types of Geological Formations of Groundwater
Groundwater is an important natural resource. The precipitation infiltrates into the ground and travels down until it reaches the impervious stratum where it is stored as groundwater. It is stored in the pores present in the geological formations such as ...
Classification of Rocks with Examples
A rock is an aggregation of different mineral constituents which form the earth’s crust. Different types of rocks possess different engineering properties that make them suitable to be used in various construction works. The classification of rocks based on different ...
Quicksand Condition – Occurrence Mechanism and Preventive Measures
Quicksand condition is the floatation of particles of cohesionless soil, like fine gravel and sand, due to vertical upward seepage flow. As sand boiling occurs, the bearing capacity and shear strength of the cohesionless soil decrease and the agitations of ...
Uniformity Coefficient(Cu) and Coefficient of Curvature(Cc) of Soil
The uniformity coefficient (Cu), curvature coefficient (Cc) and the effective size (D10) are the grading characteristics of the soil. These are the geometric properties of a grading curve that describe a particular type of soil. The features and determination of ...
