| 1 | 日本东北9.0级地震的同震与震后滑动显示文摘大部分强震都发生在海沟,那里是海洋板块向大陆板块俯冲的地方。大量矩震级MW9.0以上的地震发生在若干区域,包括智利,阿拉斯加,堪察加半岛和苏门答腊岛等。位于太平洋板块俯冲鄂霍茨克板块的日本海沟,历史记载上没有发生过MW9.0地震,除了至今震级还有争议的公元869年Jogan大地震[1](可能超过MW9.0)。然而,根据最新的大地测量资料估算的应变积累速率比已发生的板块间地震的平均释放速率要高[2~6]。这一发现又引发了这样的疑问:这些区域如何释放积累的应变。2011年3月11日发生的逆冲型MW9.0强震(下文中均称为日本东北大地震),撕裂了日本东北部的太平洋海岸板块边界。我们报道根据GPS网络监测到的地表位移确定的同震与震后滑动特征。同震滑移区域沿日本海沟方向长约400 km,与震前闭锁区域基本吻合[4]。震后滑动不仅覆盖了同震滑移区域,而且扩展到了其邻区,甚至其影响已经达到100 km深度区域,引起2011年3月25日的MW8.3地震。由于东北地震释放了积累数百年的应变,之前提到的应变积累与释放不平衡的问题可能得到部分解释。这次东北地震同时也提醒我们,即使在过去没有发生过强震的其它海沟地区,也有发生MW9.0强震的潜在危险。因此,利用空间对地形变观测技术监测应变积累,以确定强震潜在危险区是非常重要的。 | Shinzaburo Ozawa Takuya Nishimura Hisashi Suito Tomokazu Kobayashi Mikio Tobita Tetsuro Imakiire 张慧(译) 焦明若(校) | 2011 | 华南地震2011,31,3: | 30 |
| 2 | 倾斜液化场地桩基地震响应离心机试验研究显示文摘倾斜液化场地中群桩地震响应受液化土层侧向流动和桩土相互作用影响和控制,故倾斜液化场地中桩基抗震性能问题是一个极其复杂问题。基于动态土工离心机试验来探讨考虑倾斜液化土侧向流动特点的群桩地震响应规律。试验设计不同地震强度下2个50g典型土工离心模型试验,以研究倾斜液化场地中桩土加速度、位移、桩身弯矩和土体超孔隙水压力响应特性。试验提出倾斜饱和土层的制备方法,再现倾斜液化场地中桩基础在强震作用下的破坏程度、状态和机制,并进一步对比分析试验结果,取得较好的成果,此为倾斜液化场地桩基础的抗震设计提供可靠依据,对确保液化场地桩基础的抗震稳定性和安全性具有重要意义。 | 汪明武 TOBITA T IAI S | 2009 | 岩石力学与工程学报2009,28,10: | 22 |
| 3 | 液化场地堤坝地震响应动态土工离心试验及模拟显示文摘基于动态土工离心机试验和多重剪切机构模型的有效应力分析方法,研究了不同地震强度下,液化场地堤坝的地震响应和大变形特征。动态土工离心机试验的液化场地模型,由相对密度为30%的饱和砂土构成,输入正弦波峰值分别为0.8056、1.7903和3.133m/s2。并采用有效应力分析有限元程序对堤坝的动点响应进行数值模拟,计算结果与模型试验结果相吻合。在此基础上研究了堤坝的加速度、变形以及下卧液化场地中的超孔隙水压力分布规律,分析了液化场地不同位置土层中的有效应力路径变化规律。研究得出,液化场地堤坝顶和坝趾在地震作用下会发生较大的沉降和侧向扩展,且随地震强度加大而增大。堤坝下卧浅层液化土的超孔隙应力比相对较小但其体积变形较大,坝顶的残余沉降可达1.4m,地震中堤坝底部土体同自由场地土体的有效应力路径和应力-应变特征不同。土工离心机试验结果同数值解析结果基本吻合。 | 汪明武 Susumu IAI Testuo TOBITA | 2008 | 水利学报2008,39,12: | 14 |
| 4 | 强震动条件下的桩土相互作用动态土工离心试验研究显示文摘基于动态土工离心模型试验来研究强震动条件下液化土同桩基础的相互作用问题。设计了4个典型土工离心模型试验来研究桩土的加速度、位移等地震响应特性,再现了位于液化土地基上的实际桩基础在大地震下的破坏程度、状态和机制,并进一步对比分析试验结果,取得了较好的成果,为桩基础的抗震设计提供了可靠依据,具有重要意义。 | 汪明武 Tobita Tetsuo Iai Susumu | 2005 | 岩石力学与工程学报2005,24,A02: | 10 |

| 7 | Superior mesenteric artery syndrome:Diagnosis and management显示文摘Superior mesenteric artery(SMA)syndrome(also known as Wilkie's syndrome,cast syndrome,or aorto-mesenteric compass syndrome)is an obstruction of the duodenum caused by extrinsic compression between the SMA and the aorta.The median age of patients is 23 years old(range 0-91 years old)and predominant in females over males with a ratio of 3:2.The symptoms are variable,consisting of postprandial abdominal pain,nausea and vomiting,early satiety,anorexia,and weight loss and can mimic anorexia nervosa or functional dyspepsia.Because recurrent vomiting leads to aspiration pneumonia or respiratory depression via metabolic alkalosis,early diagnosis is required.The useful diagnostic modalities are computed tomography as a standard tool and ultrasonography,which has advantages in safety and capability of real-time assessments of SMA mobility and duodenum passage.The initial treatment is usually conservative,including postural change,gastroduodenal decompression,and nutrient management(success rates:70%-80%).If conservative therapy fails,surgical treatment(i.e.,laparoscopic duodenojejunostomy)is recommended(success rates:80%-100%). | Akihiko Oka Muyiwa Awoniyi Nobuaki Hasegawa Yuri Yoshida Hiroshi Tobita Norihisa Ishimura Shunji Ishihara | 2023 | World Journal of Clinical Cases2023,11,15: | 2 |
