Abstract：Abstract：Research purposes： Rotary penetration test is a new in-situ testing method that has broad application prospect. It has high efficiency in exploration depth, continuous repeatability, rapid test, economic benefit and other advantages. In this paper, in order to expand the application field and scope of rotary penetration testing technology, a foundation settlement calculation method was proposed based on the rotary penetration testing technology. The empirical calculation formula of foundation settlement was established and verified by engineering examples. Research conclusions：（1）A new calculation method of foundation settlement was proposed based on rotary penetration test, and the corresponding empirical calculation formula was established. （2）All required parameters to calculate the foundation settlement could be obtained by in-situ test of rotary penetration without drilling, sampling and consolidation test. This method could avoid the inconvenience of undisturbed sampling and discrete results of consolidation tests, and reduce the period and cost of engineering exploration. （3）The method could not calculate the settlement of the foundation reinforcement area, which could be calculated by using the formula of the compression deformation calculation of reinforcement zone for composite foundation.（4）The results can provide a simple new calculation method for foundation settlement and promote engineering applications of the rotary penetration technology.
