Pile Design and Construction Practice Book PDF by Michael Tomlinson & John Woodward

Piling rigs are a common place feature on building sites in cities and towns today. The continuous introduction of new, more powerful, and self-erecting machines for installing piled foundations has transformed the economics of this form of construction in ground conditions where, in the past, first consideration would have been…continue reading →

Pile Foundation Construction Procedure

We have already defined the pile foundation, its type and importance in case of low bearing ground conditions. But this post will mainly deal about the procedures and steps that are undertaken for the construction of pile foundation. Pile foundation construction procedure is not simple as it involves heavy machinery…continue reading →

Tunnels and their stability mechanisms

Tunnels and their stability mechanismsIntroductionTunnels can be defined as underground construction for the connection between two destinations to build up an effective means of transportation. Tunnels are made for various purposes such as Railway transportation, for highways, for water supply and for communication cables etc. Tunnel construction has several benefits…continue reading →

What is Stepped Foundation

The natural surface of ground is not always level and mostly to such an extent that there may be a considerable slope either across or along or both across and along the site of most buildings.Where the ground floor is to be at or just above ground level at the…continue reading →

What are fender Piles?

The piles used to protect concrete deck or other water front structures from the abrasion or impact that may be caused from the ships or barges (when they are tied up at the desk), are called fender piles. The fender piles are originally made up to timber.Sometimes a man-made marine…continue reading →

What Is Under-reamed Pile Foundation?

Many times during soil exploration, geotech engineers have to face soils that are very likely to undergo volumetric changes due to moisture variation underneath the ground surface. This expansion and shrinkage can cause distress which is very dangerous and critical as far as bearing of the foundation is concerned. This is…continue reading →

What Is Cofferdam And Its Types?

Yesterday I was watching documentary on a Bridge having piers founded in the water and was wondering how engineers and constructors are able to lay pile foundation in such a high-speed flowing water of river.  After research of few hours I have got a handful of knowledge about the technique…continue reading →

What Are Secant PILES?

You might have heard a structure called Cofferdam, it is a structure built to divert water either of river or groundwater so as to make a dry, safe and sound environment for the construction activity to carry out. This cofferdam can be a typical retaining wall type or it can…continue reading →

Methods of Reducing Soil Liquefaction

It is extremely difficult and impractical to prevent liquefaction of soil in the field when the susceptible zone extends to a large depth. It is generally best not to construct buildings and other structures at sites prone to liquefaction. Because the remediation of the liquefaction hazard is quite expensive, it…continue reading →

Types of Soil Liquefaction

Liquefaction is a state of water- saturated, mostly cohesion-less soil whose shear strength is reduced to zero due to pore water pressure produced by vibration during an earthquake. The soil starts behaving like a liquid.For more details on Soil Liquefaction Please refer to Original Article about Soil Liquefaction.Following are the…continue reading →

Sand Boils due to Liquefaction

Liquefaction produces so many drastic effects and damages to the structures and foundations build over its effected soil. The buildings and structures whose foundations are on soil affected by liquefaction will experience a sudden loss of support which will result in drastic and irregular settlement of the building causing cracking…continue reading →
