In this utility model, the measuring method whether karst collapse occurs is as follows:
By karst collapse on space-time with critical soil cave as boundary, be divided into Inter-collapse phase and surface subsidence stage, set up seepage tensor for two different phases and cause the mechanical model that collapses.
(1) to Inter-collapse phase, Pu Shi natural balance arch theory is utilized to set up the maximum height expression formula of critical soil cave:
Wherein, the span (m) of D pressure arch
The solid coefficient of the fk soil body
The thickness (m) of the h cap rock soil body
Hmax critical soil cave height (m)
The applicable elements of this formula is: h >=2hmax, i.e. karst cave body need to reach certain buried depth and could form stable soil arch, as buried depth is shallower, is directly entered the surface subsidence stage.
(2) to earth's surface Subsidence Stages, limit of utilization balance theory sets up seepage tensor collapse mechanical model, obtains the mechanical model expression formula of following earth's surface Subsidence Stages:

Negative pressure of vacuum (kPa) in △ P karst cave body
This formula presses the least favorable condition consideration that karst occurs, it is assumed that following condition:
1. heavy showers causes cap rock water level abruptly increase, and Karst water table is quickly passed with solution cavity, underground river,
Forming Trend of Groundwater Descent Funnel, water level is down to below basement rock top board, and in the hole body that subsides, vapour pressure is 0；
2. Collapse Pit is tubbiness, and slump body diameter is identical with Cave diameter D.
As K ＜ 1, generation of subsiding；As K=1, the body that subsides is in state of limit equilibrium；As K ＞ 1, stable.
(2) determination of critical water pressure Pcr
Solution cavity cave height is disclosed owing to being only capable of boring in monitoring section, its diameter D is difficult to actual measurement, for obtaining this parameter, 7 karst collapses recorded on the one hand can using for reference district, select monitoring point adjacent to subsiding cave diameter as this point critical collapsed diameter (generally 3～7m) nearby；On the other hand, because current monitoring point not yet occurs surface subsidence, i.e. show that hole body is in stable～state of limit equilibrium, the cave height that can disclose according to boringInverse goes out Cave diameter D, is revised in combination with having sent out the cave diameter that subsides in district.
Above example is only in order to illustrate the technical solution of the utility model, it is not intended to limit, although executing example with reference to previous examples this utility model has been described in detail, it will be understood by those within the art that, it is according to can modifying the technical scheme that foregoing embodiments is recorded, or its portion of techniques feature is carried out equivalent, and these are revised or replace, and do not make the essence of appropriate technical solution depart from the spirit and scope of technical solutions of the utility model.
