DYNAMIC RELIABILITY ANALYSIS ON RETAINING DIAPHRAGM WITH STRUTS OF DEEP EXCAVATION DURING CONSTRUCTION |
| |
| Abstract: | This paper presents the concept of dynamic strength reliability and dynamic rigidity reliability of retaining diaphragm during construction.A method of dynamic reliability assessment based on Monte Carlo SFEM is suggested for the safety of retaining diaphragm.By using the method,the dyanmic reliability of diaphragm embedded in rock during construction of the deep excavation for the northern anchorage block of Runyang Suspended Bridge is analyzed and discussed in detail. |
