摘要

吸式安装的裙边基础，通常被称为吸式沉箱，越来越多地用于各种海上应用。在设计沉箱时，岩土工程师必须考虑安装过程以及现场性能。本文的目的是介绍在粘土中安装沉箱的计算方法。对于粘土场地，通常使用沉箱作为锚，裙长(L)与直径(D)之比高达5。提出了在沉箱内施加吸力和不施加吸力的情况下，确定开放式圆柱沉箱基础抗侵穿能力的计算方法。在预测和病例记录之间进行比较。另一篇论文描述了在砂土中安装的计算过程。最后，在这里对安装在各种土壤中的评论，而不是均匀的粘土或沙子沉积物。

Design procedures for installation of suction caissons in clay and other materials

Suction-installed skirted foundations, often referred to as suction caissons, are increasingly being used for a variety of offshore applications. In designing a caisson a geotechnical engineer must consider the installation process as well as the in-place performance. The purpose of this paper is to present calculation procedures for the installation of a caisson in clay. For clay sites, the caisson will often be used as an anchor, with the ratio of the skirt length (L) to the diameter (D) as high as 5. Calculation methods are presented for determining the resistance to penetration of open-ended cylindrical caisson foundations with and without the application of suction inside the caisson. Comparisons between predictions and case records are made. A companion paper describes the calculation procedure for installation in sand soils. Finally, comments are made here about installation in a variety of soils other than homogeneous deposits of clay or sand.

期刊介绍： The objectives of the Association shall be the promotion of co-operation among geotechnical societies in SE Asia; and the assistance to member societies who have limited number of members. Now there is only one combined web titled: AGSSEA-SEAGS. SEAGS & AGSSEA encourage the submission of scholarly and practice-oriented articles to its journal. The journal is published quarterly. Both sponsors of the journal, the Southeast Asian Geotechnical Society and the Association of Geotechnical Societies in Southeast Asia, promote the ideals and goals of the International Society of Soil Mechanics and Geotechhnical Engineering in fostering communications, developing insights and enabling the advancement of the geotechnical engineering discipline.
