Caissons are huge semi deep concrete foundation which provide enough balance and stability for its superstructure and usually is embedded on a previously improved ground. It is also applicable to use replaced granular soil to act as in minor concentrated loose sands.
Sheet pile walls are usually installed to support temporarily or permanently the excavations in unstable soils. In large depth the sheet piles are usually supported from lateral movements by anchorage or reciprocal supports.
Soil nailing is a passive method for stabilizing deep excavations and steeply lands. This method can provide enough safety factors against any possible rupture limits during and after excavation and also limits the ground movements and sometimes is applied for strengthening existing unstable ground.
