...-slopes. Generally the canalis lined with puddle clay. 5. Since its completion in 1808, the canal has suffered from a series of breaches, leaks and other geotechnical difficulties. Major breaches occurred in 1945, 1960, 1982 and 1985.The last three were all between bridges 35 and 36. The 1945 breach...

... and the Paper has dealwt ith the particularquestion of the susceptibility of puddle clay cores to hydraulic fracture. This susceptibility is related to the stresses existing in these cores. The research has been based on field measurements of in situ stress in the puddle clay cores and puddle clayfilled...
