Bealock is usually in a geological poor zone, a rock body joint crack develops, weathering unloading is serious, a stacking layer is loose and loose, and engineering properties are poor. When the road passes through the mute mouth in cutting form, because the toe excavation, loose accumulation layer easily slides unstability along its interface with the basement rock. As shown in fig. 3, in order to maintain the stability of the slope, cutting is often excavated at a small slope ratio, and the slope is graded to provide each grade of streets. And meanwhile, a retaining wall or an anti-slide pile is arranged at the toe of the slope to play a role in anti-slide. Such a procedure has certain problems: (1) the small slope ratio excavation will generate great engineering excavation amount, cause mountain disturbance with a large range and serious ecological damage, and is not beneficial to the long-term stability of the side slope. (2) The supporting and blocking structures on the two sides of the cutting play a role respectively, are not connected with each other, cannot play the maximum role of the supporting and blocking structures on the two sides simultaneously, and perform cooperative work. For example, in the road engineering where the side slopes on both sides are supported by the slide piles, when the slide piles on one side are exerted to the limit and are about to fail and the slide piles on the other side are not fully exerted, the sum of the supporting capabilities of the slide piles on both sides depends on the side with the weak supporting effect, which causes resource waste to a certain extent. (3) The compressive capacity of the reinforced concrete cannot be fully exerted.
Therefore, a structure which can meet the requirement of road passing, fully exert the maximum function of the retaining structures at two sides and has small excavation amount of a road construction mountain is required to be found, and the economic benefit maximization can be realized under the condition of ensuring the road safety.
