Problems solved by technology

However, if the dynamic compaction energy level is selected too large, resources will be wasted, and if the selection is too small, the expected treatment effect will not be achieved.

Embodiment Construction

[0031] In order to further explain the technical means and effects of the present invention to achieve the intended purpose of the invention, the specific implementation, structure, features and effects of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments.

[0032] Principle of ground radar: ground radar transmits high-frequency and very high-frequency electromagnetic waves in the form of pulses to the ground. Electromagnetic waves propagate in the medium. When encountering underground targets with electrical differences, such as cavities and interfaces, the electromagnetic waves are reflected and returned to the ground by the receiving antenna. On the basis of processing and analyzing the radar waves received by the receiving antenna, the spatial position, structure, electrical properties and geometric shape of the underground target can be inferred according to the received radar waveform, intensity...

Abstract

The invention relates to a dynamic compaction treatment method for a karst foundation. The method includes the steps that (1) rough plane distribution of underground karst of a construction site and karst cave roof burial depth data are acquired, and the construction site is divided into different blocks according to the karst cave roof burial depth data; (2) karst development condition information is obtained, local dynamic compaction tests are conducted on the different blocks, and dynamic compaction construction technical parameters of the different blocks are determined; and (3) dynamic compaction construction is conducted on the different blocks, in the dynamic compaction construction process, the treatment effect of the foundation is monitored and measured while compaction is conducted, and follow-up construction is optimized according to monitoring information. According to the dynamic compaction treatment method for the karst foundation, areas with different depths and development conditions of karst caves in the construction area are partitioned, proper construction technical parameters are given respectively, and dynamic compaction treatment is performed in different areas, so that the treatment effect is ensured, the construction period is shortened, treatment resources are saved, and the construction cost is reduced.

Description

technical field [0001] The invention relates to a method for treating karst ground with dynamic compaction. Background technique [0002] The dynamic compaction method is a method in which a heavy hammer of tens of tons (generally 8-40t) is freely dropped from a height of tens of meters (generally 6-40m) to compact the rock and soil mass. Dynamic compaction is based on the mechanism of dynamic compaction, that is, the impact dynamic load is used to reduce the pore volume of the rock and soil mass, and the soil mass becomes compact, thereby increasing the strength of the foundation soil. [0003] It is feasible to use the above dynamic compaction mechanism to deal with the special geology of karst. However, due to the different treatment depths of different dynamic compaction levels, it is not known whether the traditional dynamic compaction method can achieve the expected treatment effect for caves with different buried depths. [0004] First of all, the inability to choos...
