目前，校准室内试验用于建立现场测试数据与砂土工程性质之间的关联，并在理解现场测试中发挥着重要作用。实际和经济上的考虑要求校准室的尺寸必须是有限的，因此所选择的边界条件对结果有重要影响。评价了燃烧室尺寸对压力计试验极限压力实测值和锥体贯入度试验锥体阻力的影响。实验和数值数据表明，洞室边界的接近对致密和中等砂粒的影响是显著的，即使对疏松砂粒也可以观察到。因此，L对这一问题的解释具有重要的现实意义。德斯..。
Calibration chamber tests are currently used to establish correlations between in situ testing data and the engineering properties of sands, and play an important role in the understanding of in situ tests. Practical and economic considerations require that calibration chambers must be of limited size, and so the chosen boundary conditions have an important effect on the results. An assessment is made of the effects of chamber size on the measured values of the limit pressure obtained from the pressuremeter test and on the cone resistance values from the cone penetrometer test. Experimental and numerical data suggest that the effect of the proximity of the chamber boundaries is significant for dense and medium sand, and is observed even for loose sand. Les essais en chambre de calibration sont a present employes pour etablir les correlations entre les donnees des essais in situ et les proprietes des sables pour le calcul des fondations et jouent un role important dans l'interpretation de tels essais.
