路基填料强度(CBR值)改良的工程应用与浅析

Engineering Application and Elementary Analysis on Modification of Roadbed Stuffing Strength (CBR Value)

CBR值是衡量路基填料强度性质的重要工程指标,通过施工中对CBR值的测定可以有效的保证路基填筑的强度与稳定性能。结合实际工程,对于CBR值不满足规范要求的填料提出了改良方案,并结合技术性能和经济指标等因素,对改良方案进行了分析与比较后得出最终处理方法,并就实际工程中CBR值的理解与应用方法提出了自身的理解。

The California bearing ratio (CBR) value is an important engineering index to measure the roadbed stuffing strength property. The measurement of CBR value in the construction can effectively guarantee the strength and stability properties of roadbed filling. Combined with a practical project, this paper puts forward the modification scheme of stuffing whose CBR value does not meet the standard requirements. Combined with the factors of technical performance and economic index, this paper analyzes and compares the modification schemes, and gives the final treatment method, and according to the understanding and application method of CBR value in the practical projects, puts forward own undertaking.
