Background
With the continuous development of society, roads and bridges in China are greatly developed, the development of the road and bridge industry in China is very optimistic in recent years, but a plurality of imperfect places exist in the development process.
The roadbed is a structure formed by filling or excavation and directly supporting the rails, and is also called a line infrastructure. The roadbed is connected with the bridge and the tunnel to jointly form a circuit. The subgrade has two basic forms according to different terrain conditions: embankment and cutting, commonly known as fill and excavation. The railway roadbed is used for directly laying a track structure on a roadbed, so that the roadbed is the foundation of the track, and roadbed load bears the weight of the track structure, namely static load, and dynamic load transmitted by the track when a train runs. The roadbed and the track together form a circuit structure which is in a relatively loose connection structure form and weak in dynamic load resistance. The material for constructing the roadbed, whether filled or excavated, is mainly an earth-rock type discrete material, so the roadbed is an earth structure, is often attacked and damaged by changes of natural conditions such as geology, water, rainfall, climate, earthquake and the like, and has poor resistance, and therefore, the roadbed should have sufficient firmness, stability and durability. For a high-speed railway, the roadbed should have reasonable rigidity so as to ensure the stability and comfort of a train in high-speed running.
The quality and the strength of the roadbed are seriously influenced by inevitable introduction of impurities or defects such as local pits and even cracks in the roadbed in the construction process, and the mode of manual inspection and repair is often adopted in the prior art, so that the efficiency is extremely low, and the repair strength is poor.
