Abstract
In the paper,geological investigation and evaluation of geotechnical properties are carried out based on geotechnical engineering a-gainst the background of geological conditions of an actual project under construction.The results of the investigation show that the proposed site has poor uniformity of the upper foundation soil layer,poor uniformity of the weathering zone of the lower bedrock,and the undulation of the level of the local section is greater than 20%.Based on this,the project adopts grouted piles for soft ground treatment,and through the method of combining static load test and digital settlement sensor,monitoring and analysing the bearing capacity of pile foundation and drawing Q-s curve diagrams,and analysing the bearing capacity of different pile lengths,it is found that an increase in the length of the pile foundation will improve its bearing capacity,and the bearing capacity of the laid pile foundation meets the needs of the actual project.关键词
