Overview of rock foundation
Rock foundations generally have three basic forms: straight anchor type, platform bearing type, and embedded type. The straight anchor type and the cap type anchor the anchor bars directly into the grouted rock holes, and use the bonding force between the rock itself, the rock and the mortar, and the mortar and the anchor bars to resist the external force from the upper tower structure to ensure that the The anchoring and stable embedded type of the pole tower structure is similar to the excavation foundation, and can be used in geological conditions of strong and weathered bedrock. The straight anchor type has the advantages of simple process and low cost, while the platform-supporting type and the embedded type are remedial methods that cannot use the straight anchor type.
The principles of basic design are economic rationality, resource conservation, and environmental friendliness. The rock anchor pile foundation has the advantages of less foundation consumption, low project cost, environmental protection, and convenient construction, and is suitable for use in mountainous line projects.
The rock foundation software includes modules
and straight anchor pile foundation
This type of foundation uses anchor bolts as anchor bars to be directly anchored into the rock. Because the distance between the anchor bolts is small, only Suitable for hard unweathered or lightly weathered rock with thin covering layer. Generally, mechanical drilling is used, high-grade cement mortar is poured, and anchor bolts are bonded to form anchor piles. The top is poured with a concrete cap no smaller than the tower foot plate. When this type of foundation encounters local interlayers, the rock holes should be enlarged and each anchor screw group should be buried in one hole. This type requires good rock integrity, thin covering layer, and high drilling construction requirements, so its application scope is greatly restricted.
, Cap-type anchor pile foundation
This type of foundation connects the anchor piles and anchor bolts as a whole through a reinforced concrete cap. It is suitable for hard, medium-weathered rocks with thick covering layers and soft breezes. petrified rock. The anchor piles are anchored with mortar or fine stone concrete, and the cap is made of reinforced concrete. When the integrity of the rock is poor, the spacing between anchor bars needs to be increased or more than four anchor bars are required. Mechanical drilling is also required during construction. It is not suitable for highly weathered geological conditions, and the amount of concrete for the cap platform is large.
, Embedded foundation
This type of foundation is suitable for strongly weathered rock conditions. The embedded foundation is to pour the anchor bolts directly into the slope/concrete pier.
Three main calculation functions

, shear bearing capacity of foundation piles and rocks Force calculation
, anchor bar calculation, anchor length calculation
, anchor bar structure anchor length calculation
, anchor pile cap local pressure bearing capacity calculation
, anchor pile protective cap, bearing Calculation of the amount of concrete for platforms and foundation piles
, Calculation of the reinforcement and reinforcement ratio of the anchor pile cap
, Calculation of the length and amount of the cap steel bars
, Configuration of anchor bars and accessories
, Draw the anchor pile foundation diagram
