The history case of the rock slide in the reservoir of 200-m-high Zimapan Arch Dam (Mexico) is discussed. The problem required
the stability analysis of this rock masse with the evaluation of its volume to estimate the consequences of the rock mass
falling into the reservoir. The results of the analysis of the unstable zone with the estimated volume of 14.6×106 m3 are presented. The "Deficit of Stability Method" is described. The analysis consists in the consecutive examination of rock
blocks or wedges located on different parts of the polygonal sliding surface, beginning with the upper one.

The Çoruh River is one of the most important rivers in northeastern Turkey. Preliminary studies to determine the energy potential of this river resulted in the selection of eleven potential dam sites. The presence of large landslides at some of the sites has led to modifications to the initial proposals; for instance the Ispir dam was abandoned and replaced with the Norgah scheme upstream of the landslides. Similarly, the proposed location of the Uzumlu dam site was abandoned and a new dam site was proposed upstream of the landslide. The Havuzlu and Demirkent landslides have been investigated to assess their possible influence on the Inanli and Yusufeli dam sites. 相似文献

A protective layer(PL) is commonly reserved above foundation surface to protect the underlying rock mass during dam foundation excavation. In China, the PL of dam foundation is conventionally subdivided into two or three thin layers and excavated with the shallow-hole blasting method, even by pneumatic pick method in case of soft rock mass. The aforementioned layered excavation of the PL delays the construction of the whole project. After nearly 30-year practices, several safe and effcient methods for the PL excavation of dam foundation are gradually developed. They include shallow-hole bench blasting with cushion material(SBC) at the bottom of the hole, and horizontal smooth blasting(HSB). The PL is even cancelled on the condition that horizontal pre-split technique is employed during dam foundation excavation. This paper introduces the aforementioned two PL excavation methods(shallow-hole blasting and bench blasting) and horizontal pre-split technique of dam foundation without protective layer(HPP). The basic principles of blasting method, blasting geometry, charge structure, drill-and-blast parameters of typical projects are examined. Meanwhile, the merits and limitations of each method are compared. Engineering practices in China show that HSB is basically the optimal method for dam foundation PL excavation in terms of foundation damage control and rapid construction. Some new problems for dam foundation PL excavation arising, such as strong unloading and relaxation phenomenon that encountered in the gorge region of southwest China, are needed to be addressed; and the corresponding countermeasures are discussed as well. 相似文献

The paper discusses the magmatic rocks that form the foundation material for the Pamukluk Dam, Tarsus, Turkey. The area has
suffered extensive dyke intrusion and significant tectonic disturbance. The paper reports the results of both in situ tests
and laboratory tests on block and borehole core samples. In general, the diorites and microdiorites have suffered little alteration
and remained strong. The granophyres and less weathered acidic rocks are moderately strong while the gabbros are the weakest
materials. The elastic moduli vary between 830 and more than 3500 MPa. Pressuremeter tests indicated that for a 120 m high
dam, the settlement would vary between some 33 and 69 mm.
