No land animals were present in Florida prior to the Miocene. The largest deposits of rock phosphate in the United States are found in Florida. [1] Most of this is in Bone Valley in central and west-central Florida. [2] Extended systems of underwater caves, sinkholes and springs are found throughout the state and supply most of the water used ...
Slope stability refers to the condition of inclined soil or rock slopes to withstand or undergo movement; the opposite condition is called slope instability or slope failure. The stability condition of slopes is a subject of study and research in soil mechanics, geotechnical engineering, and engineering geology.
The soil nailing technique applied to temporarily and/or permanently stabilise natural slopes and artificial scarps is based on a fundamental principle in construction engineering: mobilizing the intrinsic mechanical characteristics of the ground, such as cohesion and the angle of internal friction, so that the ground actively collaborates with ...
Soil nailing is a remedial construction measure to treat unstable natural soil slopes or unstable man-made (fill) slopes as a construction technique that allows the safe over-steepening of new or existing soil slopes.
Slope stability analysis is a static or dynamic, analytical or empirical method to evaluate the stability of slopes of soil- and rock-fill dams, embankments, excavated slopes, and natural slopes in soil and rock.
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.
MSE walls stabilize unstable slopes and retain the soil on steep slopes and under crest loads. The wall face is often of precast, segmental blocks, panels or geocells that can tolerate some differential movement. The walls are infilled with granular soil, with or without reinforcement, while retaining the backfill soil.
The probe into the 2021 collapse of a beachfront condominium building that killed 98 people in South Florida should be completed by the fourth anniversary of the disaster, federal officials said ...
