Crosshole Logging Test of Piles Crosshole logging (CSL), designated Ultrasonic Crosshole Testing in ASTM D6760, is a non-destructive method for assessing the homogeneity and integrity of concrete in bored piles, drilled shafts and other deep foundation elements. It detects anomalous zones by measuring ultrasonic pulse transmission between access ducts installed in the pile. Principle A … Read more
Pile Integrity Testing (PIT), also known as low-strain impact integrity testing, is a non-destructive method used to evaluate the continuity, consistency and approximate physical dimensions of deep foundation elements. The test is applicable to driven concrete piles, cast-in-place piles, drilled shafts, augered piles and other deep foundation members that can respond to a low-strain impact. … Read more
Introduction Pile load testing is the most reliable method of verifying whether a pile can safely carry its design load under actual site conditions. It helps confirm the load-carrying capacity, settlement behavior, and overall quality of pile foundations before the superstructure is constructed. IS 2911 Part 4 – Load Test on Piles provides standard procedures … Read more
Discover the structure of Earth in a simple and easy-to-understand way. This comprehensive guide explains the Earth’s crust, mantle, core, seismic waves, major discontinuities, and their importance in civil engineering with clear illustrations and practical insights.
FUNCTION OF A PILE FOUNDATION The primary function of a pile foundation is to transfer load to a deeper soil or rock strata. There can be various reason that can force designers to transfer loads to deeper soil or rock strata. For example The soil at shallow depth is weak, i.e., not able to withstand … Read more
In last few years, lot of tunneling works are being executed in all over the world. One of the toughest challenge engineers face during design and construction phase is to deal with geology of that area.
What Is The Effect of Tree Roots on Building? Fast growing trees close to buildings can cause unequal settlement when active tree roots dry out the soil causing differential soil shrinkage. Shrinking clays affect the bearing capacity and lead to movement in the building, especially in shallow foundations. Tree roots can extend over a considerable … Read more
WEATHERING OF ROCK MASS ‘Weathering is the process of alteration and breakdown of rock and soil materials at and near the Earth’s surface by chemical decomposition and physical disintegration’ (Geological Society Engineering Group Working Party Report, 1995). Of particular note in this definition is that weathering is described as a process. It is not a … Read more
WEIGHT VOLUME RELATIONSHIP OF SOIL The physical properties of a soil give insight as to the identification of the soil and the determination of its characteristics and load response. These properties can be determined by performing a laboratory analysis on undisturbed soil samples obtained during the test boring process. The laboratory analysis should be performed … Read more
Design Procedures for a Building Foundation (Step by Step) Good design must not only be safe but must aim to save construction costs, time and materials. The following procedures should help to achieve this and an ‘educated’ client will recognize the importance of funding this work with a realistic fee. 1. Decide the Location of … Read more
