Embodiment Construction

[0060] Embodiments of the present invention: The specific implementation manners of the technical solutions of the present invention will be clearly and completely described below.

[0061] The specific implementation process is as follows:

[0062] Such as figure 1 As shown, a building is determined to be within the influence area of ​​the front edge of the dangerous landslide. The fertilizer tanks at the front and rear of the building are backfilled with soil, and the soil at the front of the basement is reinforced with steel pipe grouting. The sliding body at the rear is arranged m Rows of deeply buried shear pile support measures, taking unit width landslides and buildings as research objects;

[0063] Such as figure 2 As shown, the weight of the building G, the depth of the basement H, the friction coefficient of the contact surface between the basement floor and the foundation, the outer wall surface and the backfill soil of the fertilizer tank are all μ, and the mech...

Abstract

The invention discloses an overall reinforcement design method considering stability of a building at bottom of landslide. The method comprises the following implementation processes: determining that a building is located in a dangerous landslide front edge influence range, backfilling the front part and the rear part of the building with filling soil, and selecting a unit width landslide and the building as research objects; adopting a steel floral tube grouting reinforcement measure for a front fat groove of the basement of the building ti improve the physical and mechanical indexes of the composite soil body of the part, thus improving the passive soil pressure of the part on the building; adopting a deeply-buried shear-resistant pile supporting structure for the landslide on the rear portion of a building so as to resist sliding force generated by a sliding body; and finally, performing overall anti-sliding stability checking calculation on the building, so that the feasibility of the overall reinforcement design checking calculation method is verified.

Description

technical field [0001] The invention relates to a design method of a slope support structure and a reinforcement technology for emergency rescue and disaster relief, in particular to a method for verifying the stability and reliability of reinforcement measures for buildings within a landslide range. Background technique [0002] With the expansion of various construction scales, geological disasters such as slope instability and landslides occur frequently. In landslide prevention and control, especially landslide emergency rescue, not only the support and reinforcement structure design is required to be reliable, the construction is convenient and fast, and the economy is reasonable. Fully consider the safety and stability of buildings within the range affected by landslides. Existing treatment methods such as load reduction, back pressure, anchor cables, anti-slide piles and other support forms have high requirements on site conditions, and the construction period is gene...
