Soil nails were used to stabilize an 18 metres (59 ft) high slope consisting of sandy soil. This method proved to be more cost-effective, while at the same time cut down the construction time when compared to other conventional support methods. [4]: 23 Germany was the next country to investigate soil nailing.
Sand fill may be appropriate for several courses to provide a vibration damping building base, but becomes unstable in ordinary bags above 60–100 cm (24–39 in) in height. Cement, lime or bitumen stabilization can allow clay soil to withstand flooding or allow sands to be used in traditional bags with a non-structural plaster skin.
Mechanically stabilized earth (MSE or reinforced soil) is soil constructed with artificial reinforcing. It can be used for retaining walls , bridge abutments, seawalls , and dikes . [ 1 ] [ 2 ] Although the basic principles of MSE have been used throughout history, MSE was developed in its current form in the 1960s.
Sinkholes form when rainwater dissolves limestone, salt, gypsum and similar types of bedrock under the soil. Florida's bedrock is mostly limestone, making it a prime area of the country for sinkholes.
Approximately 8 acres (32,000 m 2) of soil was contaminated by wood with arsenic, chromium, and polycyclic aromatic hydrocarbons. 8% of Portland cement was used by wet weight of contaminated soil. Both in situ and ex situ processes were utilized to treat over 35,000 cubic meters of contaminated soil.
A COLE value of 0.06 means that 100 inches of soil will expand by 6 inches when wet. [2] Soils with this shrink-swell capacity fall under the soil order of Vertisols. [6] As these soils dry, deep cracks can form on the surface, which then allows water to penetrate to deeper levels of the soil. [7]
The Army Corps is currently spending $40 million to truck in 835,000 cubic yards of sand to restore about two miles of shoreline in Miami Beach, a project that will require tens of thousands of ...
