The present paper shows the results of 3D monitoring with the use of extensomet ers TM71 performed in Bulgaria in the framework of COST Action 625. This research was performed in selected areas: Simitli graben that is the most seismoactive area in Bulgaria; Madara plat eau - rock scarp with historical monument affe cted by rock toppling; East Rhodopes area - a possibly active fault zone and a large landslide. The most impressive results were established at Simitli graben area with the rate of 2.73 mm/year sinistral movement of Krupnik Fault. Local earthquakes located at NE part of the graben usually influence the movements along this fault. An acceleration of the left latera l movements during calm periods has been established, and respectively, the movements stop (or going in opposite direction) during seismic activity. At Madara site, the results from the 15 years monitoring show subsidence of rock s lices by 0.9 mm per year and si milar rate movement of the slices to South direction. Influence from Izmit earthquake, Vrancea earthquakes and local ones have been established. The monitoring of the fault at General Geshe vo Village, East Rhodopean area started in 2003. The first results show mainly gravitational movements - subsidence of NE block 1.5 mm/year., Nikolai Dobrev and Elka Avramova-Tacheva., and Obsahuje bibliografické odkazy
In this paper, results from the long-term monitoring of two deep-seated slope deformations are presented. These deformations are considered typical of the types of landslide that occur in the high mountains of the Western Carpathians. The localities are situated in similar geological settings and this has enabled direct comparison of their development over the past 30 years. The monitoring has been undertaken using the extensometric gauges, TM71. At the Parohy Site, results from the scarp area show a significant vertical displacement trend of 0.07 mm per year. At the Štrochy Site, results from the crown area show a horizontal crack opening trend of 0.015 mm per year. Monitoring is ongoing at both sites., Miloš Briestenský, Blahoslav Košťák, Josef Stemberk and Jozef Vozár., and Obsahuje bibliografii
The static analyses and assessment of the technical condition of historical buildings in the Prague Castle Area are based on observational methods to gather the basic information about the behaviour of structures. The monitoring involves a combination of different methods of surveying, crack, inclination and temperature measurements together with the monitoring of dynamic effects of traffic and nearby tunnelling activities. These methods were enhanced by line-wise measurements using a high-precision sliding micrometer and inclinometer to assess the role of subsoil and to discover potential very slow slope movements in inclined parts of the area. The problems connected with long-term stability of historical buildings are further studied with the use of static analyses and numerical models of selected buildings in the area., Jaromír Procházka, Jan Záleský, Tomáš Jiřikovský and Jan Salák., and Obsahuje bibliografii
A detailed geomorphological mapping was performed in the valley of the Losenice R., which is situated on the NE slopes of the Šumava Mts. nearby the Kašperské Hory town. The dominant characteristics of the studied area are steep slopes of the deeply incised, narrow valleys, strong fragmentation of the bedrock composed of various types of gneisses and obvious structural influence on the valley network plan. Based on the analysis of the occurrence, parameters and relative position of selected landforms, which have significance for documenting certain processes, as well as other inputs, the relief of the studied area was divided into eight genetic types of relief segments: structural, erosional, erosional-structural, structuraldenudational and erosional-denudational slopes, flat denudational ridges and planation surface remnants and finally the valley floors with the floodplain., Filip Hartvich and Vít Vilímek., and Obsahuje bibliografii
Svahovými pohyby se rozumí přemísťování horninových hmot na svazích účinkem zemské tíže. Tyto pohyby přirozeného původu i vyvolané lidskou činností patří k velmi rozšířeným geodynamickým jevům, které způsobují vážné přímé i nepřímé škody na budovách, komunikacích, liniových vedeních, důlních a vodohospodářských stavbách. Nejběžnějším druhem svahových pohybů jsou sesuvy. Mezi země silně postižené svahovými pohyby patří i Česká republika, a to zejména její východní část, která je součástí geologické jednotky Západní Karpaty, s mladým horským reliéfem, živými endogenními i exogenními procesy. Svahovými deformacemi jsou zde postiženy v průměru 3 % území, přičemž například ve flyšových horninách ve Vsetínských vrších dosahuje procento postižení území kolem 10 %. V převážné části republiky patřící ke geologicky staršímu Českému masivu, je svahovými pohyby postiženo asi 1 % území., Jan Rybář., and Obsahuje seznam literatury
The techniques of the method of the coupled modelling was substantially extended and used for solving problems connected with underground constructions for various materials and appropriate structural systems. In principle, a combination of linear effects of the external loading and material and time-dependent nonlinear change in structures was considered. Assessment of rock behaviour in surrounding of utility tunnels, solution of the structural strength below foundation, back analysis of reinforced soil slopes and studies of slopes endangered by groundwater were carried out., Petr Procházka and Jiřina Trčková., and Obsahuje bibliografii
