文章摘要

第62届朗金讲座由Lidija Zdravković教授主讲,主题为《Geotechnical Engineering for a Sustainable Society》,在伦敦帝国理工学院举行。讲座聚焦于开发强大的预测工具,以支持岩土工程设计,并与基础设施的生命周期评估相关。重点讨论了气候变化对老化基础设施的影响、海上风力涡轮机基础设计、地下热扰动和化学扰动对岩土工程基础设施的环境影响等。Zdravković教授介绍了数值模拟软件ICFEP的五个应用领域,包括海上风能结构桩基础设计、桩基础与堤坝的时间和气候变化、降雨对边坡稳定性的影响、核废料处理的模拟方法以及数据驱动的设计方法——贝叶斯推理。

朗金讲座是岩土工程领域著名的邀请讲座,由英国岩土工程协会举办,以纪念WJM Rankine教授的贡献。自1961年设立以来,已有多位岩土工程领域的杰出人物获得此荣誉,包括Ralph B. Peck、Arthur Casagrande等。由于新冠疫情,2020年和2021年的朗金讲座未能举行,因此2024年的讲座是第62届。

1. 引言

第62届朗金讲座 (Rankine Lecture)如期于2024年3月13日在伦敦帝国理工学院举行,Lidija Zdravković教授作了题为《Geotechnical Engineering for a Sustainable Society》的演讲,讲座背景参看下面的链接,在此不作赘述。讲座时长大约2小时,本公众 号已经录制了这个讲座

1.1 讲座摘要
今天,岩土工程面临着一系列日益复杂和范围不断扩大的挑战。工业界和学术界已经为应对其中一些挑战做出了努力,为发展当前和未来的安全、可持续和有弹性的社会做出了贡献。本次朗肯讲座的重点是开发强大的预测工具,以支持与一系列基础设施的生命周期评估有关的岩土工程设计,并通过具体例子说明。这些发展的关键是通过现场监测,以一致的方式将地层特征与严格的计算分析和验证相结合。讲座重点包括:

(1) 气候变化引起的天气模式条件下支持老化基础设施可持续寿命延长的研究;

(2) 在可再生能源开发中影响海上风力涡轮机基础设计的研究;

(3) 地下热扰动和化学扰动对岩土工程基础设施的环境影响。

1.2 讲座内容

在简要概述了研究框架之后,主要围绕数值模拟软件(ICFEP)讨论了5个方面的应用:

(1) 海上风能结构桩基础的设计方法

(2) 桩基础与堤坝随时间和气候的变化,主要是蠕变性能

(3) 降雨对边坡稳定性的影响

(4) 核废料处理的模拟方法(THM多相耦合)

(5) 数据驱动的设计方法---贝叶斯推理  

2. 朗金讲座简介

朗金讲座(Rankine Lecture)是岩土工程领域最早设立的著名邀请讲座,由英国岩土工程协会[British Geotechnical Association (BGA)]举办。该讲座为了纪念格拉斯哥大学(Glasgow University)土木工程教授WJM Rankine对土力学和岩土工程作出的重大贡献---特别是挡土墙的土压力理论。朗金讲座设立于1961年,比太沙基讲座【太沙基讲座(Terzaghi Lecture, 1963-2024)的设立早两年。迄今为止共有14位同时赢得了这两个讲座,他们是:

(1) Ralph B. Peck, NAE (1912-2008)

(2) Arthur Casagrande, NAE (1902-1981)

(3) Lauritis Bjerrum (1918-1973)

(4) H. Bolton Seed, NAE (1922-1989)

(5) T. William Lambe, NAE (1920-2017)

(6) Nathan M. Newmark, NAE (1910-1981)

(7) Ronald F. Scott, NAE (1929-2005)

(8) James K. Mitchell, NAE, NAS (1930-2023)

(9) Norbert R. Morgenstern, NAE

(10) Evert Hoek, NAE 

(11) Suzanne Lacasse, NAE

(12) Harry Poulos, NAE 

(13) R. Kerry Rowe, NAE

(14) Thomas D. O'Rourke, NAE

自从1961年讲座设立以来,至今年为止,总共经历了64年,2020年和2021年由于新冠疫情没有举行朗金讲座,因此2024年是朗金讲座62周年。
