项目摘要

In view of rapid globalization even in engineering profession, geotechnical design codes have been extensively reviewed in various parts of the world, especially in Europe and the North America, seemingly to arrive at eventually harmonization of the various design codes in the world. Recent trends seem that the final version of the codes are to be rewritten in a format of limit state design, reliability design (ISO2394, Eurocodes etc.) and performance based design (WTO/TBT etc.).Observing these trends, a series of the activities were initiated by a research committee entitled "Present and Future of Japanese Foundation Design and Soil Investigation in view of International Harmonization" in 1997 chaired by Osamu Kusakabe, which was followed by 'Preparation committee on drafting JGS foundation design guideline' (chaired by Osamu Kusakabe, April 2000 - March 2001), and the to 'Drafting committee on JGS foundation design guideline' (chaired by Yusuke Honjo, April 2001 - date). During these … More 6 years, we have accomplished following tasks :(1)Review the currently used foundation design codes in the world and compare them with the codes in practice in Japan.(2)Review the site investigation methods employed in the above codes and compare them with the Japanese practice.(3)Send investigation missions to Europe, North America and Australia-New Zealand, to make interviews with the code writers to obtain the most recent information on the issues and to create an information network in the world.(4)Carry out a questionnaire to geo-technical engineers in Japan to find out how the designers are selecting soil parameter values in design foundations.(5)Make some recommendations on the future of foundation design codes in Japan. This idea finally resulted to draft a comprehensive foundation design code, so called 'Geo-code 21' whose English translation of the most recent draft (Ver.2) is given in Honjo et.al (2002).These activities are carried out with close international collaborations, especially with Technical Committee 23 'Limit state design in geotechnical engineering practice' (chair, P. Day 1998-2001, Y. Honjo 2002-2005) of ISSMGE. A serious of research carried out in this project are all connected to the activities described above, and the whole picture could be understood by looking Proc. Of IWS Kamakura which is the last reference in the below list. Less

鉴于工程行业的快速全球化，岩土工程设计规范已在世界各地进行了广泛审查，特别是在欧洲和北美，似乎最终达到了世界各种设计规范的最新趋势。规范的最终版本将以极限状态设计、可靠性设计（ISO2394、欧洲规范等）和基于性能的设计（WTO/TBT 等）的格式重写。观察这些趋势，开展了一系列活动发起1997 年，以日下修为主席的“日本地基设计和土壤调查的现在与未来”研究委员会，随后又成立了“起草 JGS 地基设计指南的准备委员会”（由日下修担任主席，4 月） 2000 年 - 2001 年 3 月），以及“JGS 基础设计指南起草委员会”（由 Yusuke Honjo 主持，4 月） 2001年至今）。在这6年里，我们完成了以下任务：（1）审查目前世界上使用的基础设计规范，并与日本实践中的规范进行比较。（2）审查现场调查方法(3)派出调查团前往欧洲、北美和澳大利亚、新西兰等地，与规范编写者进行访谈，获取有关问题的最新信息，并制定解决方案。信息网络中的（4）对日本的岩土工程师进行问卷调查，了解设计者如何选择设计地基中的土壤参数值。（5）对日本地基设计规范的未来提出一些建议。这个想法最终导致起草了一份全面的基础设计规范，即所谓的“Geo-code 21”，其最新草案（Ver.2）的英文翻译在 Honjo 等人（2002 年）中给出。这些活动是在密切关注下进行的。国际合作，特别是与技术委员会的合作23 ISSMGE 的“岩土工程实践中的极限状态设计”（主席，P. Day 1998-2001，Y. Honjo 2002-2005）。该项目中进行的一系列研究都与上述活动有关。整个图片可以通过查看 IWS Kamakura 的 Proc 来理解，这是下面列表中的最后一个参考文献。
