摘要:
为评价综合管廊施工对临近堤防渗流安全影响,通过综合分析管廊施工前后堤防的渗流场差异以及渗透坡降变化,提出堤防施工渗流安全综合评价方法,并以武汉某综合管廊为例开展工程应用。研究结果表明:临堤综合管廊施工对堤防内渗流场的分布影响较大,导致堤防内渗透水流集中在管廊基坑附近,管廊基坑处承担的水头损失达89.81%;管廊基坑底渗透坡降局部增加明显,其中基坑内角处渗透坡降最大达3.29,与未施工相比增加24.91倍,临堤综合管廊施工使堤防渗流破坏风险增大。
Abstract:
In order to evaluate the influence of the construction of comprehensive pipe gallery on the seepage safety of adjacent dike,a comprehensive evaluation method for the seepage safety of dike construction was proposed by comprehensively analyzing the seepage field difference and seepage gradient change of the dike before and after the construction of pipe gallery,and the project application was carried out by taking a comprehensive pipe gallery in Wuhan as an example.The results showed that the construction of comprehensive pipe gallery near the dike had great influence on the distribution of seepage flow field in the dike,resulting in the seepage water flow in the dike concentrated near the foundation pit of pipe gallery,and the head loss borne by the foundation pit of pipe gallery reached 89.81%.The seepage gradient at the foundation pit bottom of pipe gallery increased significantly in local area,among which the maximum seepage gradient at the inner foot of the foundation pit reached 3.29,with an increase of 24.91 times compared with that without construction.The construction of comprehensive pipe gallery near the dike increased the seepage damage risk of dike.
