Description of failures and risks that are emerged from landslide measurement activities in infrastructure deformations

Abstract

Original scientific paper The occurrence of frequency of landslides that are considered parts of natural hazards continues to increase and their negative consequences affect human life, environment and urban infrastructures. In consideration of landslides that have remarkable destructive effects among the natural hazards, the importance of the engineering measurements and calculations in the geodetic network that is constructed in the landslide area plays an important role. A lot of factors affect the accuracy of the engineering measurements and calculations. Failure Mode Effect Analysis (FMEA) and Pareto Analysis methods are the effective tools in revealing these factors and alleviating their risks by taking relevant precautions. It may be possible to alleviate the risks to a minimum in the engineering measurements and calculations relevant to landslide parameters by these methods.We have attempted to alleviate failures and to take relevant precautions with FMEA and Pareto Analyses for the failures resulted in engineering measurements.

S obzirom na odrone zemlje koji među prirodnim nesrećama završavaju značajnim destruktivnim posljedicama, važnost tehničkih mjerenja i izračuna u geodetskoj mreži koja se izrađuje u područjima s odronima od velikog je značaja. Među velikim brojem čimbenika koji djeluju na točnost tehničkih mjerenja i proračuna, metode Failure Mode Effect Analize (FMEA) i Pareto Analize su učinkoviti alati u otkrivanju tih čimbenika i ublažavanju njihovih rizika poduzimanjem odgovarajućih mjera predostrožnosti. Tim je metodama moguće gotovo potpuno smanjiti rizike u tehničkim mjerenjima i proračunima relevantnim za parametre odrona. Pokušali smo ublažiti propuste nastale tehničkim mjerenjima i poduzeti odgovarajuće mjere predostrožnosti primjenom FMEA i Pareto analize.
