The paper introduced current design status of piled raft foundation.Based on de-scribing various methods used in engineering design from three respects,including design idea,de-sign methods of rafts and piles,the advantages and disadvantages of each method were analyzed,and some problems of the current design methods were pointed out,such as poor systematization,practicability and optimization,no consideration about the limit states of carrying capacity and nor-mal use,and so on.Furthermore,some countermeasures were proposed.
