| Abstract: | The pore water pressure outside of diaphragm wall of super-deep foundation pit of the sub station was monitored,and the pore water pressure distribution and characteristic with time and depth were comprehensively analyzed.The trend and stochastic terms in the pore water pressure monitoring curve of relatively impermeable layer were extracted by means of the polynomial function and least square principle,and the prediction analysis of the pore water pressure was carried out.The predicted result was close to ... |
