Mackinac Bridge: Construction of the Most Aerodynamically Stable Suspension Bridge
The Mackinac Bridge in Michigan is a bridge of ideal, assured aerodynamic safety secured without sacrificing either economy or graceful proportions. The design of the bridge, with a main span of 3800 ft., was predetermined scientifically, in final form, without ...
5 Disastrous Foundation Failures in New York City
Foundations are susceptible to movements if the applied loads are not in proportion with the design, causing a downward motion known as settlement. Settlement can be tolerated by the structure provided the loads do not exceed the allowable bearing pressures. ...
4 Important Non-Destructive Geophysical Soil Investigation Methods
The geotechnical investigation for any worksite is preceded by the preliminary geological-geotechnical survey. This consists of an on-site superficial survey, sometimes involving small investigation activities, such as the opening of shallow pits and shafts. Usually, the field visit is preceded ...
Top 12 Soil Problems in the World
Soil is used for a variety of purposes including cropping, pasturing, gardening, forestry, agroforestry, construction, etc. The aim is always to find the most suitable type of soil to get the best outcome. Especially in agriculture, the desired yield of ...
Void Forms in Foundation Construction: Their Types and Applications
Void forms are sacrificial formwork members designed to provide a space between the concrete foundation and expansive soil, i.e., to protect the foundation from the heave of the underlying soil. They also offer a temporary support formwork for recently poured ...
How to Construct a Bored Pile Foundation?
Bored pile foundation or drilled shaft foundation is a commonly used foundation for supporting heavy vertical loads. It transfers the load to the soil below or rock strata with sufficient bearing capacity and reduces the settlement of the structure. The ...
All You Need to Know About Directional Boring
Directional boring or horizontal directional drilling (HDD) is a trenchless technology employed to install underground pipes without affecting the area above the borehole. Directional boring is used for the installation of utility pipelines and conduits. Most underground boring contractors use ...
