摘要

以重庆市城镇建设和交通枢纽工程形成的典型工程堆积体为研究对象，采用野外双环入渗法对工程堆积体入渗特征、影响因素及入渗模型适宜性进行研究，筛选重庆市典型工程堆积体最优入渗模型。结果表明：（1）工程堆积体初始入渗率可达23.20 mm/min，随着入渗时间的延长，入渗速率逐渐降低，30 min瞬时入渗率为2.38~11.32 mm/min，稳定入渗率为1.81~9.05 mm/min；（2）工程堆积体的初始入渗率、稳定入渗率、平均入渗率、30 min入渗率、60 min入渗率和渗透总量均表现为中等变异，变异系数为36.42%~57.49%；（3）工程堆积体初始入渗率、稳定入渗率、平均入渗率和渗透总量与容重和含水率均呈负相关关系，与总孔隙度呈正相关关系；稳定入渗率、平均入渗率和渗透总量与60~40，40~20，20~10，10~5 mm碎石含量呈负相关关系，与5~2 mm碎石含量呈正相关关系；（4）不同工程堆积体回归模型的拟合效果存在差异，其决定系数R2依次为Kastiakov模型（0.899） > 通用经验模型（0.893） > Horton模型（0.870） > Philip模型（0.867），Kastiakov模型拟合效果优于通用经验模型、Horton模型和Philip模型，可以较好地模拟和预测重庆市工程堆积体入渗过程和入渗能力。

Abstract

Taking the typical engineering accumulation of urban construction and transportation hub project in Chongqing as case study

the infiltration characteristics

influencing factors and suitability of infiltration model were explored by using field double-ring infiltration

and the best infiltration model of typical engineering accumulation in Chongqing was filter out. The results indicated that:(1) The initial infiltration rate of engineering accumulation was 23.20 mm/min. The infiltration rate decreased gradually with time

and the 30 min-infiltration rate was 2.38~11.32 mm/min and the stable infiltration rate was 1.81~9.05 mm/min; (2) The initial infiltration rate

stable infiltration rate

average infiltration rate

30 min-infiltration rate

60 min-infiltration rate

and total infiltration of each engineering accumulation showed medium variation and the coefficient variation was 36.42%~57.49%; (3) The initial infiltration rate

stable infiltration rate

average infiltration rate

and total infiltration of engineering accumulation had negative correlations with soil bulk density and soil water content

while positive correlations with total soil porosity existed. The stable infiltration rate

average infiltration rate

and total infiltration of engineering accumulation had negative correlations with 60~40

40~20

20~10

10~5 mm gravel content and had positive correlations with 5~2 mm gravel content; (4) There were differences in the fitting effect of the regression models with different engineering accumulations and the ranking of R2 from high to low was:Kastiakov model (0.899) > common empirical infiltration model (0.893) > Horton model (0.870) > Philip model (0.867). The fitting effect of Kastiakov model was better than the common empirical infiltration model

Philip model and Horton model

and which could be used to simulate and predict the infiltration process and infiltration capacity of engineering accumulation in Chongqing.
