排水砂井广泛应用于岸坡、堆场、路堤、土坝、油罐等工程的软基处理。但应用于海堤工程,国内尚缺乏经验。在我省大官坂围垦工程海堤中,采用排水砂井处理软基取得成功,从而加快了工程进度,节省了土石方量。目前全部海堤工程已告完成。现将情况及试验结果介绍如下。 Drainage sand wells are widely used in soft foundation treatment of bank slope, yard, embankment, earth dam, oil tank and other projects. However, applied to the seawall project, the domestic is still inexperienced. In the seawall of Dajinsaka Reclamation Project in our province, the successful use of drainage sand wells to treat soft soils accelerated the progress of the project and saved earthwork volume. At present all the seawall project has been completed. Now the situation and test results are as follows.
