Method for realizing pile foundation scheme optimization by applying a geological exploration data rapid reading system

Abstract

The invention discloses a method for realizing pile foundation scheme optimization by applying a geological exploration data rapid reading system. The method comprises the following steps: A, readingdata; B, drawing a calculation table, and calculating the characteristic value of the vertical bearing capacity of the single pile at each hole point; C, merging to form a plurality of subsection areas, and dividing the subsection areas into a plurality of pile types; D, drawing a curve of the ratio of the pile length to the designed bearing capacity of the single pile and a curve of the ratio ofthe pile length to the engineering cost of the single pile to obtain a curve of the ratio of the designed bearing capacity of the single pile to the engineering cost of the single pile, and finally obtaining the relation between the pile length of the pile type and the total cost according to the known total bearing capacity; And E, storing the hole point data into a dz file which can be identified and read by interference modeling software through a vba language compilation applet. The method has the advantages that geological exploration data are directly read, the working efficiency is improved, the hole point calculation result can be analyzed through one key, fine design is achieved, the calculation result is direct and accurate, and unnecessary design waste is reduced.

Description

technical field [0001] The invention relates to a pile foundation scheme optimization method, in particular to a pile foundation scheme optimization method realized by using a geological survey data fast reading system. Background technique [0002] The pile foundation has a high bearing capacity and a wide range of applications, and is currently the most widely used form of deep foundation. At present, the general process of pile foundation design is that the geological survey unit first conducts site survey and submits a report, and the designer analyzes the geological survey report, grasps the site characteristics in general, and calculates and analyzes each exploration hole According to the data in the report, input the data of each hole point into morgain or similar structural calculation software for calculation), the upper structure calculates and transmits the load to the foundation, according to the load conditions and taking into account the economy, select the pil...

Problems solved by technology

[0003] Due to the large amount of hole point data, the design unit needs to manually input it into the software after receiving the geological survey report, which is time-consuming and laborious, and there is also the possibility of input errors. The work may take several days or even longer, and the hole point calculation and the basic overall calculation, because the software is different and the file format is different, this entry work has to be done twice, which seriously affects the work efficiency; because the input process is too cumbersome, the hole During the overall analysis of points or foundations, designers often select relatively unfavorable or typical individual hole points for input program calculation based on visual geological survey reports. This is based on the designer’s personal subjective judgment. For complex geological conditions, construction For projects with large sites, this method is easy to miss key points and cause hidden dangers; at present, the basic plan is evaluated based on multiple conditions, and then it is drafted based on experience and then verified by trial calculation. The verification process often has partial dissatisfaction and needs to be adjusted repeatedly Finally, the results meet the safety, practicability and economy several times. This adjustment is also time-consuming and laborious, and there is a certain requirement for the experience of the designer. Since the selection of the pile foundation is based on experience, the calculation cannot exactly meet the specification standards. A certain margin and a conservative design often cause unnecessary waste and increase the project cost

[0004] Therefore, the existing pile foundation scheme design process requires manual input of geological survey data, low work efficiency, too much reliance on the designer's personal subjective judgment, unable to achieve refined design, easy to overestimate the project cost, and cause waste of materials
