Embodiment 1

[0030] Such as Figure 1-3 As shown, a landslide combined long and short anti-slide reinforcement pile structure according to the present invention includes several long anti-slide piles 1 arranged at intervals along the lateral direction of the landslide body.

[0031] A short anti-slide pile 2 is set between two adjacent long anti-slide piles 1, and the distance between the long anti-slide pile 1 and the adjacent short anti-slide pile 2 is 5m-10m. Both the long anti-slide pile 1 and the short anti-slide pile 2 are reinforced concrete piles.

[0032] The top of the long anti-slide pile 1 is higher than the top of the short anti-slide pile 2, the bottom of the long anti-slide pile 1 is lower than the bottom of the short anti-slide pile 2, and the bottom of the long anti-slide pile 1 The top is higher than the potential overtop sliding surface 4 , and the bottoms of the long anti-slide pile 1 and the short anti-slide pile 2 are lower than the deep weak sliding surface 3 .

Embodiment 2

[0035] Such as Figure 1-3 As shown, a kind of design method of the landslide combined long and short anti-slide reinforcement pile structure as described in embodiment 1 of the present invention, comprises the following steps:

[0036] 1. calculate the landslide sliding force of the whole described deep weak sliding surface 3 of the landslide;

[0037] 2. Calculating the stability of the landslide under the reinforcement of the long anti-slide pile 1 within the short anti-slide pile 2 and the short anti-slide pile 2 elevation of the deep weak sliding surface 3;

[0038] 3. judging step 2. whether the safety factor of the landslide after reinforcement meets the design requirements, and if it does not meet the requirements, then increase the pile section and / or pile embedding depth of the long anti-slide pile 1 and the short anti-slide pile 2;

[0039] ④Repeat steps ② to ③ until the landslide safety factor meets the design requirements;

[0040] 5. calculate the landslide sli...

Abstract

The invention discloses a landslide combined long and short slide-resistant reinforcing pile structure and a design method. The reinforcing pile structure comprises a plurality of long slide-resistantpiles arranged at intervals in the transverse direction of a landslide body, a short slide-resistant pile is arranged between every two adjacent long slide-resistant piles, the tops of the long slide-resistant piles are higher than a potential top-crossing sliding surface, and the bottoms of the long slide-resistant piles and the bottom of the short slide-resistant piles are lower than a deep soft sliding surface. According to the landslide combined long and short slide-resistant reinforcing pile structure, the long slide-resistant piles and the short slide-resistant piles are arranged at intervals in the landslide body, so that the stability of the deep soft sliding surface and a combined sliding surface is enhanced; and the large landslide pushing force of the deep soft sliding surfaceis resisted by the long slide-resistant piles and the short slide-resistant piles, and the landslide pushing force of the combined sliding surface is resisted through the long slide-resistant piles, so that the landslide reinforced engineering investment can be saved.

Description

technical field [0001] The invention relates to the field of landslide reinforcement engineering, in particular to a landslide combined long and short anti-slide reinforcement pile structure and design method. Background technique [0002] Landslides are distributed in a large number of mountainous areas in my country. When the stability of landslides is low and endangers the safety of construction projects or personnel and property, it is necessary to reinforce the landslides. When the landslide is a deep and thick landslide, the traditional high cantilever anti-slide pile project requires large investment and high construction risk. If anti-slide keys are only set near the sliding surface, the risk of over-top failure of the landslide due to uncertain factors will easily occur. Therefore, it is of great significance to propose a new anti-sliding reinforcement structure and design method. Contents of the invention [0003] The object of the present invention is to provid...
