SCP Method at Sea

Improvement Principle	Compaction, Consolidation and Reinforcement
An improvement method whereby strong compacted sand piles are created in ground to form composite ground at cohesive soil. This increases the shear resistant strength, and at the same time, it stabilises early settlement to reduce the consolidation settlement rate. For sandy ground, it increases the relative density, thus enhances the shear strength.

Advantages	Applicable to all kind of soils such as sandy soil, cohesive soil and organic soil etc.
	Able to acquire the effect of compaction, enforcement & consolidation drainage simultaneously.
	Able to use crushed stone and slug etc. as fill material.
	Possible to execute deep improvement by big construction machine.
Disadvantages	Vibration and noise is big.
	Upheave happens by installation of SCP.
	Possibility that water can be polluted during installation.
Applicable Ground	Mostly all types of soil such as sandy soil, cohesive soil, and organic soil etc.
Objectives	Structural Foundation,Prevent Settlement,Prevent Slip Circle,Prevent Liquefaction
Improvement Effectiveness	Sandy Soil	Increase Shear Strength
		Prevent Liquefaction
		Reduce Settlement
	Cohesive Soil	Promote consolidation
