本文介绍了汕头港多用途件杂（1－2）泊位后方堆场采用真空联合堆载预压法处理软基的施工情况，并对粘土密封墙的施工工艺、检测方法进行了进一步规范。得出结论：在表层存在4～12．5m深厚砂层的地质条件下，结合粘土密封墙技术，采用真空预压加固法是可行的。
This paper introduces the construction of the soft foundation in the rear yard of Shantou Port multipurpose complex (1-2) berth with vacuum combined preloading method. The construction technology and testing methods of clay sealing wall are further regulated. It is concluded that under the geological conditions of 4 ~ 12.5m thick sand layer on the surface, it is feasible to use the method of vacuum preloading in combination with the clay sealing wall technology.
