- 摘要:
- 西气东输二线广深支干线交叉穿越东深供水管道，交叉穿越段由于受各种因素制约，安全间距不符合国家现行规范要求。为保证供水管道安全，制订了安全措施。穿越处的输气管道采用D 1 500 mm、壁厚31.5 mm的钢套管进行保护，并置于灌注桩基础上，钢套管外设混凝土箱涵保护。经过结构安全复核，在输气管道发生爆炸情况下，附加压力对供水管道的整体稳定性、地基承载力及结构的影响在安全要求限度内。截至目前，广深支干线已安全平稳运行近一年。
The safety space between the intersecting place of Guang-Shen branch pipeline of the Second West to East Gas Pipeline and Dong-Shen water supply pipeline is not in accordance with the requirements of the current national standard. Therefore, the safety measures are worked out to ensure pipeline safety, that is, the gas pipeline at the intersection is protected by a steel sleeve pipe of D 1 500 mm × 31.5 mm and placed on jet grouting piled foundation, and a concrete box culvert is set to protect the sleeve pipe. The structural safety check shows that the effects of additional pressure from gas pipeline explosion on integral stability of the water supply pipeline, the foundation bearing capacity and the structure are within the safety requirements.2013,6(6): 33-36 收稿日期：2013-6-13DOI：10.3969/j.issn.l001-2206.2013.06.008作者简介：张安(1980-)，男，山东单县人，工程师2006年毕业于中国石油大学(华东)工程力学专业，硕士现从事油气长输管道建设与管理工作。参考文献：
