| 摘 要： | 自上个世纪80年代万荣县城关变电站出现地裂缝,其形成原因一直存在较大的争议。通过实际调查,变电站地裂缝的发展与场地浸水有直接关系。地裂缝对城关变电站的破坏主要表现为墙体和地面出现拱翘、开裂和水平错动变形。利用探槽、探井揭示地表浅层地裂缝的发育状况,总结了地裂缝的特征,结合场地土层的自重湿陷性,分析了变电站内出现墙体和地面破坏的原因,探讨了万荣城关变电站地裂缝的成因机制。

| Abstract: | Since the 1980's,the ground fissures had happened in the suburb transformer substation of Wanrong County.The arguments about the genesis of the ground fissures were never stopped.Based on the field investigation,the development of the fissures was related to the immersion ground.The arching,cracking and dislocation of the ground and the structure wall were caused by the fissures in the substation.The characters of the fissures were disclosed by the exploration trenches and inspection wells.According to the ... |
