This book summarizes the results of the Symposium on Field Instrumentation for Soil and Rock. Major session topics include: Field Data Acquisition and Data Management Geotechnical Instrumentation of Landfills Instrumentation for Project Cost ManagementThe following is an overview of the information presented in this volume.Three papers address field instrumentation associated with culverts and buried pipe. McGrath et al. presented the results of backfilling on pipe of various material and diameter. Unique methods were presented for instrumenting corrugated pipe. Webb et al. discussed instrumentation of concrete and corrugated steel arch culverts with spans of about 9 m. Various instruments were installed to monitor structural strain and deformation and culvert-soil interface pressure. The arches were backAfilled and tested under live loads. Deformation measurements of the walls of the culverts were made with a custom-built laser device developed for this research. Yang et al. presented convincing eviAdence on earth pressure instrumentation of concrete box culverts beneath highway backfill that curArent ASSHTO guidelines underestimate earth pressures perhaps as must as 30%.
