基于地下管廊施工建筑垃圾产生特征的定量预测模型的建立

以浙江省宁波市地下管廊施工为研究对象，通过现场调研和建筑施工进度跟踪，建立了工程渣土、废弃混凝土、工程泥浆3种建筑垃圾的定量预测模型。结果表明:预计产生程渣土为83891.21 m3、废弃混凝土为4837.34 m3、工程泥浆为11435.27 m3。与真实值相比，模型的相对误差分别为8.6%，4.9%，3.5%，均低于20%，可认为三类建筑垃圾预测模型的建立有效。

ESTABLISHMENT OF QUANTITATIVE PREDICTION MODEL BASED ON CHARACTERISTICS OF WASTE GENERATED IN UNDERGROUND PIPELINE GALLERY CONSTRUCTION

In this paper, the construction of the underground pipe gallery in Ningbo, Zhejiang province was taken as the research object. Based on the field investigation and the tracking of the construction progress, the quantitative prediction models of three kinds of construction wastes, including engineering slag, waste concrete and engineering slurry, were established. The predicted results showed that 83891.21 m3 of waste soil, 4837.34 m3 of waste concrete and 11435.27 m3 of engineering mud were expected to be produced. Compared with the real value, the relative errors of the model were 8.6%, 4.9%, 3.5% respectively, which were all lower than 20%. Thus, three kinds of construction waste prediction models were proved to be effective.
