Description
Technical field
The present invention relates to the anti-skid structure of big ability in civil engineering, in particular to the anti-skid structure of a kind of big ability of w type and
Construction method.
Background technique
Landslide will cause great threat to engineering safety, be in geotechnical engineering using reasonable engineering measure harnessing landslide
Important Hazard control technology, the maximally efficient Traditional project measure measure in processing landslide are using friction pile and combinations thereof knot
Structure, his principle are mainly to pass through the lateral drag resistance of friction pile since gliding mass slides down the raw Thrust of Landslide of movable property, are guaranteed
Slip mass is stablized.But traditional friction pile still has disadvantage, if stake section is excessive, resists Thrust of Landslide and very big pile body is needed to cut
Face even needs several campsheds while carrying out supporting, causes cost higher, long in time limit；In addition, single-pile stress is uneven, every pile
It is independently arranged, very likely so that entire anti-slide pile structure is failed because leading to whole destruction after local failure when gliding mass slides.
Domestic and international project personnel have conducted extensive research antiskid structure, mainly to change pilework combining form and reach
Improve structure overall stiffness, reasonable stress etc., cost and change functionally are little.For example, traditional friction pile is led to
It crosses linking beam and is changed into "door" type stake, chair form stake, framed bent stake, H type stake etc., these structure major functions are also resistant to landslide and push away
Power, structure overall stiffness are centainly promoted, but cost is not saved substantially, and difficulty of construction increases instead.
