Description

A kind of dam construction cross-operation Steric clashes frequency test method
Technical field
The present invention relates to a kind of dam construction cross-operation Steric clashes frequency test method, this method be mainly used for for It weighs cross-operation Steric clashes and quantitative analysis tool is provided.
Background technology
Dam construction process is complicated, and management and control difficulty is big, is especially limited by construction technology and construction site, work of respectively constructing Sequence closely connects, and multiple working procedures generally require to be carried out at the same time, and is also easy to produce a large amount of cross-operation.
Cross-operation is spatially penetrated through, is overlapped in working range, and same race occupies limited space, will be formed Steric clashes, and the frequency occupied is higher, time more long then Steric clashes cause the possibility of calamity bigger.Cross-operation space rushes It is prominent, increase the probability that crosses for the construction workers and concrete transportation mechanical movement track such as close a position, vibrate, unicom human body Or the hazard-affected bodies such as equipment fall the contact channel that object etc. endangers energy with eminence, easily form the constructions such as object strike, falling object from high altitude Safety accident.
The currently used frequency that Steric clashes are distinguished with mood operator, the method excessively rely on expertise, are easy It is influenced by subjective factor, is unable to the temporal frequency of accurate quantification Steric clashes.It is empty simultaneously for dam construction cross-operation Between the measurement that conflicts mostly from space angle shorter mention time aspect, mostly from the less design and construction of design aspect Aspect also lacks a practicable method.
