建筑垃圾填埋路基沉降预测的三点-星野法
Subsidence prediction of subgrade filled by construction waste based on three point-hoshino algorithm
摘要
Abstract
In order to solve the contradiction between the rapid development of construction industry and shortage of sand and gravel aggregate, achieve the purpose of construction waste being applied in highway subgrade, the characteristics of subgrade subsidence filled by construction waste have to be mustered. Hoshino algorithm is improved based on the basic idea of three point method, and model of Three Point-Hoshino algorithm is established. The features of Three Point-Hoshino algorithm is analyzed and then the scope of its reasonable collocation is discussed. Combining with measured data collected in highway subgrade filled by construction waste in North Loop from Xi'an to Xian Yang , three points, expanded hyperbolic method, Hoshino algorithm and three point-Hoshino algorithm were respectively studied. By comparing the results of data analysis, it can be found that the application of three point-Hoshino algorithm in subgrade engineering filled by construction waste is feasible, it not only has a high precision, fit and practicability, but also has advantages of simplicity and convenience for calculation. Also, it avoids the fluctuation of the data by using the three points in measured curve. This method provides reference for the subsidence prediction and extension of subgrade filled by construction waste, has significantly social and economic benefits.关键词
