Analysis of Settling Character and Prediction Result of the Red Sandstone Dynamic Compaction Embankment

Abstract:

The particles of red sandstone will be softened under the dry-wet-cycle condition which leads to the decrease of red sandstone strength. In addition, the roadbed of red sandstone shows larger post construction settlement and differential settlement under mixing effects of the external load and the soil weight. For this reason, the research on the change of characteristics of settlement of red sandstone dynamic compaction embankment was conducted, adopting unequal interval grey model and equal-dimensional new information prediction model to predictively analyze the result of settlement variation. The results show that the results of equal-dimensional new information prediction model is much closer to the measurement, which means this prediction model is more applicable for the settlement prediction of dynamic compaction embankment. Consequently, practical reference could be provided for analogous project.
