Abstract
On the basis of the previous work, combined with the test piles collected from Shenyang area, this paper makes a detailed study of the current standard single safety factor design pile base method to the probability limit state design pile base method. The main work is statistical analysis, calculation of reliability index, analysis of the main factors affecting the reliability index of static pressure pipe pile and the analysis of its sub-coefficient coefficients, the reliability of its carrying capacity analysis has made a useful exploration.
Highlights
1 Introduction In Our country, pile-based engineering as a part of geotechnical engineering is an important field of reliability theory application, and static pressure pipe pile as a new pile type, so it needs to be studied for reliability
The calculation value of the vertical bearing capacity of single pile is calculated by the empirical formula recommended by the pile foundation code, so the reliability level of the bearing capacity parameter table of the empirical formula method can be indirectly reflected by comparing the reliability analysis with the trial design
In the process of calculating the reliability index of vertical bearing capacity of single pile, in addition to the above resistance distribution, the comprehensive load effect distribution of pile top is used, including the dead load effect G and live load effect Q acting on pile top
Summary
In Our country, pile-based engineering as a part of geotechnical engineering is an important field of reliability theory application, and static pressure pipe pile as a new pile type, so it needs to be studied for reliability. Since its research object is a collection of one or more minerals, the engineering properties of the rock depend to a large extent on its mineral composition. With the application of reliability analysis method in geotechnical engineering, the realization of reliability design is the inevitable trend of the development of pile-based engineering in the future. The pile-based specification is in the transition stage from the fixed-value method to the approximate probability method, which requires a large number of systematic statistics
