The new version of overhead transmission line tower foundation design software is upgraded in accordance with the "Technical Regulations on Overhead Transmission Line Foundation Design"/ Revised version. The document was compiled for the first time by Beijing Lily Chen Yunzhi.
The main content and differences of the upgraded version are briefly described below
According to the "Concrete Structure Design Code", the concrete design parameters and the design parameters of ordinary steel bars and prestressed steel bars have been revised.
According to the "Technical Specifications for Construction Pile Foundations", the relevant content of pile foundations will be adjusted and revised.
The additional component coefficient of the cast-in-place pile foundation should not be less than the table. Partial coefficients of suspension towers are used to withstand straight lines (corners and suspended corner towers). Partial coefficients are used to withstand tension at corners, terminals and long-span towers.
The strength grade of the concrete used in the foundation should not be lower than that of the foundation. When the foundation uses steel bars with a strength grade of or above, the concrete strength grade should not be lower than that.
The concrete strength grade of pile bodies, caps and connecting beams should not be lower than.
The requirements for the placement form, pile diameter and spacing of the cast-in-place pile foundation are added to the micro-pile foundation. The layout forms include various arrangements of straight piles and network-structured inclined piles. For the pile foundation layout part, inclined single piles, single piles, etc. The inclination angle of the pile should not be greater than 0 degrees.
The design diameter of micro piles should be selected, and the design pile length should not exceed twice the pile diameter.
The center distance between cast-in-place piles should not be less than twice their design diameter. For expanded bottom piles, it is also required that the center distance is not less than (when not greater than, the design diameter of the enlarged end) or + (when greater than).
Regulations on reinforcement of the cast-in-place pile body: when the diameter of the pile body is (), the minimum reinforcement ratio should not be less than (the higher value is taken for small-diameter piles). The minimum reinforcement ratio of Baihe cast-in-place piles has been upgraded, and different normal section reinforcement ratios are adopted according to different pile diameters.
The size of the expanded bottom end of the expanded base cast-in-place pile foundation specifies the ratio of the expanded bottom end diameter to the pile body/, which should be determined based on the bearing capacity requirements, the soil characteristics of the side of the expanded bottom end and the bearing layer at the pile end, and the base expansion construction method. The / for dug piles should not be larger than / for bored piles. The slope of the side of the expanded bottom end should be determined according to the actual hole formation and soil self-supporting conditions. / is preferable, sandy soil is preferable, and silt and clay soil are preferable. The ground at the bottom end of the expansion should be in the shape of a pot bottom, and the height of the arrow is optional ().
The stirrup density stipulates that for pile foundations subject to large horizontal loads, pile foundations subjected to horizontal ground vibrations, and when calculating the compressive bearing capacity of the pile body considering the action of the main reinforcement, the stirrups in the range below the pile top and within the liquefied soil layer The ribs should be dense and the spacing should not be greater than 1. In addition, Baihe adopted the Grade A Institute's suggestion to add the extension range of the pile stirrup density area, so that designers can flexibly set the length of the density area.
The horizontal force acting on the third foundation pile or composite foundation pile under the standard combination of horizontal force load effects.
Determination of the characteristic value/formula of single pile vertical bearing capacity for calculation of pile downward pressure bearing capacity, and the safety factor.
For the determination of the characteristic value formula of the vertical bearing capacity of composite foundation piles considering the cap effect. Two formulas are used when the ground vibration is not considered and when the ground vibration is considered.
Pile uplift bearing capacity is calculated according to the standard combination of load effects. The uplift force of a single pile or foundation pile is calculated.
Calculation of pile horizontal bearing capacity and displacement.
According to the relevant provisions of the "Technical Specifications for Construction Pile Foundations", the pile body bearing capacity and crack resistance are calculated, and the pile foundation cap's bending resistance, punching, shearing and local compression strength are calculated. Coupling beams should be reinforced based on internal forces.
The proportional coefficient value of the horizontal resistance coefficient of the soil foundation on the side of the pile. The standard value of the ultimate side resistance of the pile. The standard value of the ultimate end resistance of the cast-in-place pile. The pull-out coefficient of the cast-in-place pile. Internal friction and resistance angle. Cohesion. Stability calculation of the soil on the side of the pile.
