Abstract: Based on 38 flat dilatometer tests（DMT） and nearly 4000 p ieces of data from the tests in Shanghai,the ranges of the horizontal coeffici ent of subgr ade reaction, Kh ,in different soft soil layers and the relationships of Kh with depth are particularly analysed. And their variation are also summaried. In addition, the calculated Kh are compared with the corres ponding va lues in the code.These conclusions can be used in the designs of ex cavation, tunnel and lateral-load piles in Shanghai.
