| Abstract: | In this paper,using the block stress analysis function of ALGOR,the solid element stress analysis is carried out for the local anchor block before grouting and after tension of prestressed tendon.According to the stress analysis resultsand distribution law of the anchor block,the size and reinforcement ratio of anchor block is designed.It is a great practical significance to avoid the cracking of anchorage block and increase the effectiveness of prestressing force. |
