| Abstract | The lateral loading of the pile in soil media is a complex problem. The solution to this problem needs a thorough understanding of the reaction of pile and soil when it is loaded horizontally. This problem was understood as early as 1887, where Winkler (subgrade reaction approach) defined a solution to this problem by the introduction of springs. The spring constant replaced the soil-pile response, and till date, it's being refined to mirror this non-linear relationship of load-deflection. From Winkler (1887) to API (2000) this method is improved in such a way that it is used commercially all over the world. This research evaluates a relationship of soil response-deflection of pile curve on a linear path, also defined as subgrade reaction modulus with depths and soil properties on basis of lateral load tests done on cohesionless soils in Nakhon Ratchasima. For the relationship of subgrade reaction modulus (initial) with depths, the lower and upper limits to Reese (1974) values are defined for silty sandy soil in this research. This research also defines a new relationship between subgrade reaction modulus (initial) and friction angle. It is found that the soils in Nakhon Ratchasima show the lower value of Kh than suggested API (2000) values, which is due to the presence of silt in the soil. |
