4.Results showed that the temperature distribution of the traditional embankment was asymmetrical; the asymmetrical status was changed after ripped-rock revetment was installed and the soil under the ripped-rock was cooled obviously; the ripped-rock revetment could cool embankment and adjust the temperature difference between the north-facing slope and the south-facing slope; the ripped-rock revetment was an available technique to protect embankment from thawing settlement and longitudinal cracks in permafrost regions.

7.With the idea of integration of mechanics, electronics and hydraumatic, integrated manufacturing system and intelligent technology, the new-type high-efficiency stone-throwing machine is accomplished in this thesis on the base of analysis of dam structure, and the shortcomings of the current equipments.
8.The whole process of breakwater riprapping construction was monitored by the prototype monitoring device buried in the sand soft nappe.
9.The temperature properties conditions of a traditional embankment and a ripped-rock embankment were contrasted by laboratory experiments.
10.Technical thorny problems met during construction of cast-in-situ piles at riprap backfilling area and corresponding countermeasures are expounded to serve as a reference for similar engineering.
