Abstract

Ramhlun Sports Complex is situated at the eastern limb of Aizawl anticline, Mizoram. Landslide took place in August 2012 which badly affected 16 houses. Due to presence of tension cracks, 38 houses are vacated within a safe time, but dismantled and 10 buildings are collapsed in August 2013. This affected 195 persons of 41 families. A geological investigation was performed; representative soil samples are analyzed as Atterberg’s limits, CBR (California bearing ratio), OMC (optimum moisture content) and MDD (maximum dry density), respectively. Instrumentations and monitoring of the movement using crackmeter and tape extensometer also done for two years. The CBR and MDD values are too low as compared to the safety standards, while moisture content is too high. This may show that the movement and erosion rate may be high. The movement was relatively high when rainfall increases. It was observed that, the area is not suitable and unsafe for settlement; constructions of road/ pavement are not recommended.

印度Aizawl Ramhlun体育综合体滑坡地质调查与监测

Ramhlun体育中心位于米佐拉姆邦Aizawl背斜的东部。2012年8月发生山体滑坡，16栋房屋严重受损。由于存在张力裂缝，38栋房屋在安全时间内腾空，但在2013年8月被拆除，10栋建筑倒塌。这涉及41个家庭的195人。进行了地质调查;代表性土样分别采用阿特伯格极限(Atterberg’s limit)、加州承载比(CBR)、最佳含水率(OMC)和最大干密度(MDD)进行分析。用裂纹计和胶带延伸计对其运动进行了两年的测量和监测。CBR和MDD值与安全标准相比过低，而含水率过高。这可能表明运动和侵蚀速度可能很高。当降雨量增加时，移动相对较高。有人指出，该地区不宜定居，也不安全;不建议进行道路/铺装工程。
