Abstract: The settlement characteristics of the underlying soil layer of composite ground are studied systematically; through comparison of the settlements , by proper numerical modeling tests for composite ground, two-layered soil, artificial ground and natural ground with different improvement parameters, such as replacement ratio and elastic modulus ratio between pile and soil. Finally, a new settlement calculation method for underlying soil layer of composite ground is proposed．

Key words: composite ground, two-layered soil, natural ground；underlying soil layer
