The main types of surveying, made during the construction of cable-stayed bridges in the city of Vladivostok. Among them: the geodetic staked basis, survey work in the construction of piers and installation of anchors to mount guys pole and span, geodetic support for installation, metal core, geodetic monitoring of cable-stayed bridge in the construction process of its construction.
The implementation technique of land measuring at construction of Mariinsky theatre second stage in Saint Petersburg is presented. Basic steps of these works, such as designing, creation and monitoring of supporting geodetic network, land measuring at the establishment of experimental trench, land measuring at substracture construction of the theatre, precipitation and circumferential building careens supervision are investigated in detail.
The issues of creating high-altitude networks to support the construction of large and out-of-grade bridges are considered. The main attention is paid to the transfer of marks through large water obstacles by methods of geometric and trigonometric leveling. Recommendations are given on methods of performing leveling on ice for rivers with stable ice cover, as well as for transferring marks on rivers in the absence of a stable ice cover. During transfer of marks the possibility of using modern electronic total stations is considered. Concrete examples of works on transfer of marks by leveling on ice (bridge crossing of the Kama river several kilometers long) are given, and also experience of creation of a height network during construction of the cable-stayed bridge through the Neva river in Saint Petersburg with the help of high precision levels and electronic total station is described.
The experience of using SDL30 electronic level during tests of the Trinity Bridge in St. Petersburg conducted in May 2003 is described. The deflections of spans were determined by the results of high-precision geometric leveling. The characteristics of the level used and some test results are given. The use of electronic levels significantly reduced the time of leveling and perform a large amount of work by one team of surveyors. It is proposed to use the electronic level, which allows to speed up significantly the measurement process and get rid of the routine work of processing the results.
