路堤荷载下刚-柔性桩复合地基应力特性研究   总被引：1，自引：0，他引：1  

朱奎  徐日庆  毛西平  张天山 《煤田地质与勘探》2005,33(6):46-49

介绍了温州瓯海大道桥头路堤采用低强度砼桩和水泥搅拌桩组合复合地基处理桥头跳车问题。通过在路堤下埋设钢弦式压力盒,获得了路堤下低强度砼桩、水泥搅拌桩以及土的应力比数值随时间的变化规律,并分析了三者荷载分担比随时间的变化特性。现场测试结果还表明,路堤荷载下桩土应力比要比刚性承压板下小得多,其研究成果可为路堤下刚-柔性桩复合地基设计提供有益参考。   相似文献   

Prompt seismic data sharing for the 2021 Maduo earthquake in Qinghai province,China          下载免费PDF全文

An M_S7.4 earthquake struck west China in Maduo county, Guoluo prefecture, Qinghai province on May 22, 2021, at 2:04 Beijing time (18:04 UTC on May 21, 2021), which broke the quiet period of Chinese mainland for 1382 days without earthquakes of magnitude 7 or higher. The analysis of the seismic data sequence would play an important role in the in-depth study of the Maduo earthquake and the Bayan Har block. The Institute of Geophysics, China Earthquake Administration (CEA), compiled observation data recorded through 57 broadband seismometers within 500 km of the earthquake epicenter and intended to share for further researches in earthquake science community. The shared dataset included waveforms of the event and its sequence with magnitudes of 3.0 or higher that occurred between May 22–31, 2021 with a sampling rate of 100 sps along with the continuous waveforms of 20 Hz and 100 Hz. Additionally, the seismic instrument response files also were shared. The event and continuous waveform records could be downloaded by submitting a request through the web platform of the Earthquake Science Data Center of the Institute of Geophysics, CEA (www.esdc.ac.cn).  相似文献   

An accessible seismological dataset of 2021 Yangbi MS6.4 earthquake          下载免费PDF全文

A M_S6.4 earthquake occurred on 21 May 2021 in Yangbi county, Dali prefecture, Yunnan, China, at 21: 48 Beijing Time (13: 48 UTC). Earthquakes with an M3.0 or higher occurred before and after the main shock. Seismic data analysis is essential for the in-depth investigation of the 2021 Yangbi M_S6.4 earthquake sequence and the seismotectonics of northwestern Yunnan. Institute of Geophysics, China Earthquake Administration (CEA), has compiled a dataset of seismological observations from 157 broadband stations located within 500 km of the epicenter, and has made this dataset available to the earthquake science research community. The dataset (total file size: 329 GB) consists of event waveforms with a sampling frequency of 100 sps collected from 18 to 28 May 2021, 20-Hz and 100-Hz continuous waveforms collected from 12 to 31 May 2021, and seismic instrument response files. To promote data sharing, the dataset also includes the seismic event waveforms from 20 to 22 May 2021 recorded at 50 stations of the ongoing Binchuan Active Source Geophysical Observation Project, for which the data protection period has not expired. Sample waveforms of the main shock are included in the appendix of this article and can be downloaded from the Earthquake Science website. The event and continuous waveforms are available from the Earthquake Science Data Center website (www.esdc.ac.cn) on application.  相似文献

PATRONAGE RATES OF SUPERMARKET SHOPPING CENTERS,SAN ANTONIO,TEXAS*     

Richard C. Jones 《The Professional geographer》1991,43(3):345-355

The neighborhood supermarket shopping center is an increasingly important element of the suburban retail landscape. An analysis of patronage differentials for such centers in San Antonio, TX, reveals that both competitive share and retail mix factors are important. Correlation analysis of a patronage density index with locational and management variables indicates that center and store visibility, distance from a regional mall, retail mix (offering of goods appropriate to a small center), and size of center (smaller is better) were the most important explanatory factors in center viability.  相似文献
