In situ measurement of CBR concrete modulus.Choice of the type of dam in morocco (static loads and earthquake cases).

The Young's modulus of roller compacted concrete is rarely measured. However, it has a direct influence on the dam behavior and especially for static loads during earthquakes. In many cases, static and dynamic calculations are done with modules copied from other study. This dam was studied using in situ module measurements that contribute to a choice of the type of dam and the choice and the choice of materials from borrow pits near the dam

Contribution of geophysical methods to the detection of underground cavities in salt series. Development in different projects in Morocco (roads, rail, etc…)

As part of the geotechnical studies of a road project, a geophysical investigation by electrical tomography, microgravimetry, and boreholes, was carried out in order to locate if the areas can present or not a risks of ground instability along the road alignment. The road is located near a rock salt mine. This geophysical survey had demonstrated that the area may present major risks for the stability of the road platform. This risk is related to the existence of large expanses of saliferous rocks.The dissolution and exploitation of salt provoked underground voids under the future road. The results of this geophysical survey have allowed the designer office to propose more suitable solutions to solve this problem or even the possibility of shifting another site
