| Abstract: | The horizontal coefficient of sub grade reaction K h can be obtained from the flat dilatometer test (DMT). However, there are many influencing factors for horizontal coefficient of sub grade reaction, so the calculation formula is quite complicated. For the convenience of its application in engineering, this formula is simplified using DMT in this paper. With the tables and curve regression formula of the coefficients, the calculation steps of the practical method become simpler. It can be found that the maximal error with the practical method is less than 2 % for the data of some projects in Shanghai. |
