【正文】 s. The identification of horizontal shear deformations can offer an explanation (Figure 4), additional to geological structures and the conventionally defined pressive horizontal strains, for the occurrences of these deformational features.6. Management of Subsidencerelated Risks to Linear Infrastructure Items – The results of this study suggest a need to review the adequacy of risk management systems for important linear infrastructure items such as roads, rails, canals or pipelines, if these management systems have been developed based primarily on conventional subsidence models taking into consideration parameters predicted or measured along the lengths of such infrastructure items and/or if the features in questions do not have sufficient capacity to resist or acmodate lateral movements or shear deformations.7. Survey Practices As discussed above, to obtain properly defined shear strains or principal strains, the survey practices need to be changed. The suggested change is related primarily to the layout of survey grids, for example, 3D surveys of two (or multiple) parallel grid lines separated by an appropriately defined distance.SUMMARYBased on the investigation of the NSW coalfield measurement, this paper analysis the horizontal shear deformation on civil structure influence. This paper research the application of the horizontal shear deformation in the subsidence engineering and risk management system. Finally, the author put forward concerning the horizontal shear deformation field research direction and the prospect of certain.ACKNOWLEDGEMENTThe assistance by NSW Mine Subsidence Board with field investigations and data analysis in relation to civil structures is specifically acknowledged.
