Bachimen landslide

located in Fujian Province

China

is the current largest landslide occurred during the highway construction; monitoring is the important content among landslide dynamic design and information construction. A large scale monitoring system is built in this landslide

this paper discusses the monitoring system design

in situ layout of monitoring facilities and testing methods in detail. Monitoring items consist of surface displacement

horizontal displacement of landslide body and anti-sliding piles

soil pressure behind anti-sliding piles

tensile force of anchor cables

cracks and underground water level. Based on the synthetic analysis of typical monitoring results

sliding direction

slip surface

displacement of landslide body

the variation of anchor cables’ force and underground water level are all obtained

which provides direct proofs not only for dynamic remedial design

but also for the safety construction. Furthermore

the monitoring system makes it possible for the landslide deformation and residents’ on the landslide are all far away from abnormal serious condition. In the result

the remedial construction keeps safe and engineering cost is greatly saved

which will provide significant reference for those relevant landslide monitoring projects.
