颍河倒虹吸是南水北调中线禹州和长葛段最大的河渠交叉建筑物，为了解倒虹吸工程施工期基础及管身的变形情况，对施工全过程进行了安全监测，并对建筑物基础监测成果进行了分析。分析认为：由于建筑物上部自重逐渐增加，底板下沉量也随之加大；底板界面应力大小与建筑物箱体自重、回填物荷载以及水压力荷载等相关；基础渗透压力主要受外水压力作用较为明显。
潁河倒虹吸是南水北調中線禹州和長葛段最大的河渠交扠建築物，為瞭解倒虹吸工程施工期基礎及管身的變形情況，對施工全過程進行瞭安全鑑測，併對建築物基礎鑑測成果進行瞭分析。分析認為：由于建築物上部自重逐漸增加，底闆下沉量也隨之加大；底闆界麵應力大小與建築物箱體自重、迴填物荷載以及水壓力荷載等相關；基礎滲透壓力主要受外水壓力作用較為明顯。

Yinhe inverted siphon works is the largest river-canal crossing structure in Yuzhou-Changge section of Middle Route Project of South-to-North Water Diversion. In order to master the deformation condition of foundation and pipe body of inverted siphon, the monitoring was conducted in the whole construction period. The analysis shows that the settlement of bottom plate interface increases with the gradual increase in self-weight of upper structure, the stress of bottom plate has relation with the box weight of structure, backfilling load and water pressure etc. , the seepage pressure is obviously influenced by water pres-sure.
