建筑废料用于筑堤的材料特性研究

Study on material properties of construction waste used for sea dike

建筑废料用于筑堤是一种有效利用废料的良方。结合国内某建筑废料筑堤工程,在总结国内规范对筑堤材料要求的基础上,提出了一种建筑废料可用于筑堤的材料要求,并利用数值模拟方法计算该种建筑废料作为回填堤心料时海堤的侧向变形、沉降及整体抗滑稳定。通过实测海堤监测数据进行理论和实际的对照,进一步提出了建筑废料用于筑堤时应重点关注容重这一物理指标,并提出了其取值范围为16.5~17.0 kN/m^(3)。

Using construction waste for sea dike is a good way to effectively use the waste.Combined with a domestic construction waste sea dike project,on the basis of summarizing the requirements of domestic codes for the sea dike materials,a material requirement that construction waste which can be used for sea dike construction were proposed.Meanwhile,the numerical simulation method was used to simulate the lateral deformation,settlement and overall anti-sliding stability of the sea dike when the waste was used as the core material.Through the comparison between the theoretical calculation of numerical simulation and the actual monitoring data,it is further proposed that the physical index of bulk density should be paid more attention when building embankment with construction waste,and the range of its value is 16.5-17.0 kN/m^(3).
