DENG Ya-hong, PENG Jian-bing, FAN Wen, et al. Study on regression analysis method and programming of critical stable depth of burial of hidden holes in loess under roadbed[J]. 2008, 29(6).DOI:
an elastoplastic numerical analysis is made to analyze the critical burial depth of hidden holes in loess under the roadbed subjected to the dynamic load (FWD). In order to reduce the effect of wave reflecting on artificial boundary
transmitting boundary and semi-infinite elements are respectively used to treat the lateral and underside boundary. Based on the numerical analysis
a regression analysis method using finite numerical results of critical depth is developed; and the calculation program "LDMC" is compiled. Finally
a validity check of the program is made;and it is shown that the result has relatively good precision and completely satisfies the needs of projects.
